@curiousercreative I squashed your commits and edited the changelog to make it shorter (people reading the changelog can click the links to the issue and PR to read more). The commit still shows you as the author. Thanks for the contribution.

@micbar please get the appropriate developer to review this. And I guess @davitol might have some access already to a test Google Drive where he can manually reproduce the problem and test the fix.

Note: minor codecov fail because this PR changes GoogleDrive-specific code that will not be covered by unit tests.

And I guess @davitol might have some access already to a test Google Drive where he can manually reproduce the problem and test the fix.

Reproduced and tested the fix. With the fix dangling dot disappears and it is possible to download the file.
