[Gui] Qt error in log when opening file save dialogs

Regression from v42. Based on comment.

1. Open Log.
2. Enable User Interface DETAILS log.
3. Click "Create Sequence" on Start Page.
4. In "Create Sequence" dialog that appears, open sequence save dialog.
   Current state: log twice shows extra (unnecessary, useless) message "QWindowsNativeFileDialogBase::selectNameFilter: Invalid parameter 'All files ( * );;FASTA ( *.fa *.mpfa *.fna *.fsa *.fas *.fasta *.sef *.seq *.seqs)' not found in 'All files ( * ), FASTA ( *.fa *.mpfa *.fna *.fsa *.fas *.fasta *.sef *.seq *.seqs), GenBank ( *.gb *.gbk *.gen *.genbank)'."
