Fixes profile full-image view bug

The bug occurs when you're viewing an image full-view, then you either:
1) Switch to another conversation and return, or
2) Re-download the profile.
When you do that, the profile displays nothing at all (trying to view
image in full, but displays nothing instead).
Fixed my goofup with option checkboxes

Checking & unchecking ShowNotifications wasn't immediately updating the
visibility of the other two - which is strange, I could've sworn it was
working before...
