Copy action of the context menu is broken

[vladimiry]

It currently works properly only in one case - Tutanota accounts view. Might be related to the recent Electron.js version upgrade.

The workaround is using copy hotkey instead of the menu action, like ctrl+c.

Here is the issue related to the original implementation #11

Copy/paste context menu actions got fixed, it will be a part of the upcoming release.

Here is the related issue electron/electron#15219. So as originally assumed, the problem has arrived with Electron v2 => v3 upgrade. Nevertheless implemented workaround resolves the issue for now.
