UI: Use proper close file dialog for "Restore Last Session"

Was showing a simple confirm dialog, even if the file didn't contain
unsaved changes. The confirm dialog would also show up when choosing
"Restore Last Session" from the splash screen right after startup, which
is weird.

Instead show the proper file closing dialog that allows saving, but only
if there are actually unsaved changes.
