EXT-8539 FIXED Fixed title of alpha mask not save if renaming it from 'Editing' panel.

Bug happened because name change was not explicitly  listed as sufficient reason to save a wearable. So saving failed for alpha masks with only names changed.
Other wearables didn't have this problem because they passed precondition even if only name was changed thanking to checks that included visualparams.

- Made name change explicitly a sufficient reason to proceed with saving a wearable.
