UGENE-5798 is done UGENE has at least two importers that looks differently.
- ACE Importer: firstly asks about opening type, secondly suggests format conversion if that was selected
- APR Importer (Vector NTI Alignment format): has all options in one dialog (opening type and destination URL)
Make all importers look the same.
Note that there are also SAM/BAM importers as well!
