Open Report file dialog doesn't save previous locations as oposed to other file dialogs like Open Test Suite, Open Work Directory.
How to reproduce:
1. Open workdirectory
2. Open Report->Open and open a report
3. Open Report->Open again. Default directory will be the directory where JavaTest was run.
Expected behaviour: Open Report dialog will be opened with directory that contains previously opened report like it's done for Open Test Suite and Open Work Directory dialogs.
