Jointed track segments aren't exported (Android & iOS)

[Zirochkabila]

Description

If we join track segments into one and export them:

1. Through share
2. Through the export file
3. Via Cloud
4. Between devices with the same operating system and different

the imported file will be displayed without joined segments (setting is not saved during export)

Steps to reproduce

1. Create a track with many different segments
2. Open Track > Track > Join segment (or Appearance > Join gaps (iOS))
3. Menu > My places > Tracks > Find that track > Three dots > Shared (or Open Track > Actions > Shared (iOS)) > Telegram > Delete existing track > Import from Telegram (On the same device or on a device with a different OS)
4. Menu > My places > Tracks > Find that track > Long press > Three dots > Shared > Continue > Telegram > Delete existing track > Import from Telegram (On the same device or on a device with a different OS)
5. Menu > My places > Tracks > Find that track > Three dots > Rename > Save > Menu > Settings > OsmAnd Cloud > Local changes > Find track > Three dots > Upload local version > Go back to My places > Delete existing track > Restart OsmAnd > Go to the Cloud > Local> Download renamed track (On the same device or on a device with a different OS)

Actual result

In all cases, on both operating systems, the track will be without joined segments

Expected result

If the track was imported with Jointed segments, this setting is saved in the exported file, and the track (when imported) is displayed with the jointed segments

@vshcherb We need to understand how to display the merged segments after import:

1. By automatically activating the “Join segments” function _(Joined gaps - iOS) and displaying it in the UI menu of the track
2. Or by deleting individual segments and creating one single segment when exporting
3. Something else

The bug has been reproduced. Here's a track file you can use for testing: Test_Multi_Segment_Track.zip.

Steps to Reproduce:

1. Join Segments:

   • Android: Navigate to Track > Join Segment.
   • iOS: Go to Appearance > Join Gaps.

2. Export and Re-import Methods:

   • Sharing:

     • Go to My Places > Tracks, select the track, tap three dots > Share via Telegram.
     • Delete the existing track and import the shared file (on the same device or a different OS).

   • Cloud Upload:

     • My Places > Tracks, select the track > Rename.
     • Go to Menu > Settings > OsmAnd Cloud > Upload the local version.
     • Delete the track, restart OsmAnd, and download the renamed track from the cloud.

Actual Result:

The imported track does not retain the joined segments on either Android or iOS.

Expected Result:

Jointed segments should be preserved after importing the exported track.

And the identified issues:
After saving the current track, on iOS the saving to a .gpx file and the DB settings for appearance (getSplitType, splitInterval, current_track_gradient_palette) are not implemented.
