Fix saving new profiles
When using the "Apply" button in the "Create new profile" dialog, the profile was saved but the dialog remained in the "new profile" state. This meant that when clicking on "Apply" again or accepting the dialog, it saved the profile from scratch instead of editing the existing one. The ProfileManager interpreted that as a rename because the "Name"/"UntranslatedName" properties were set and decided to delete the profile at its "old" (== current) path.
