Update mafiles removal logic and changelog URL generation

- Fixed crash: MaFiles collection in MainVM is now a new ObservableCollection. Manual removal from collection is omitted
- Improved logic for moving mafiles to "removed": file extension is now always correct and name conflicts are handled more reliably
- Github workflow: Changelog URL in update.xml now uses repository name only for correct links
- On MaFiles collection change, PerformQuery is called to update search results
- Fixed parameter order in mafiles renaming result string to match localization
