Sentry Crash Report:

Description Anna Medonosova 2020-11-13 11:26:57 UTC 
SUMMARY
When trying to save a file, which was opened as JPG, to the native KRA format, JPG file is saved instead of KRA. The native file dialog on Android does not allow me to select a mime type; the suffix of the file name I entered is not considered.

STEPS TO REPRODUCE
1. Open a JPG file 
2. Make a change
3. File -> Save As, rename the file to ‘testfile.kra’

OBSERVED RESULT
On disk, there is a file called testfile.kra.jpg, which is a JPG, not KRA.

EXPECTED RESULT
I would expect either being able to select a mime type in the file dialog or that the saving process selecting a mime type for the file according to the suffix I input.

Android: don't set nameFilters when exporting

Android docs suggest two ways to pass mime info to the Storage Framework
1. Intent#setType() -- when mimetype belongs to some specific category e.g image/*
2. Intent#EXTRA_MIME_TYPES -- for disjoint ones.

But Qt always uses the first mimetype in the list as setType, which for certain
concrete mimeTypes (like image/jpeg), defaults the extension to .jpg which
we/user can't change.
