Fix crash regression for ApplicationWindow on Mac

This fixes a recent regression following the integration of
change:

7cc1656fef21e6bdc044968a79f0a41155357c29
(Make sure menu bar has a parent window ...)

As it now consistently crashes on mac in several of the
Qt Quick Controls examples, it is critical that it gets into
the release branch.

tst_QFileSystemModel: don't expect ~/Documents to exist

For me, this test failed because I don't have a Documents folder in my
home directory, even though that's what's returned from QStandardPaths
as the first DocumentsLocation.

Fix by falling back on the home directory if documentPaths.front()
does not exist.
