FATAL EXCEPTION on file save

I press on the csv file on the unencrypted room and it successfully saves.
But riot stops:

I have similar issue with .pdf .docx and .xlsx files. Click and Riot crashes. Click and hold and I'm given the option to save.

I had the same issue in another app after I got an Oreo phone. Not sure why it doesn't trigger for images or videos but I found a possible solution below.

The exception was before caught (see 55593b7), but the sharing was not working then

We have to fix this before the next release.

Ok, fixed
