[Testman] Missing/Bad selection (count) reset

1. Load https://reactos.org/testman/
1r. 'Found 10 Results! 0 Tests selected for comparison'.
2. Select a result.
2r. 'Found 10 Results! 1 Tests selected for comparison'
3. Change 'Source'. (i.e. KVM to VBox.)
4. Click 'Search'.
4r. 'Found 9 Results! 1 Tests selected for comparison'.

'selected' should be reset to '0'.
