[android] Crash when Import Bookmarks button is pressed

[biodranik]

It happens when there is no app to show a folder selection dialog. A proper fix should catch the exception and show a more detailed error to a user, maybe recommending installing some apps that can handle OPEN_DOCUMENT_TREE intent ("Files" app? Something else?)
