Allow divergence in API

[rakoo]

I'm using pleroma which doesn't have the same api:

• /api/v1/preferences doesn't exist
• verified_at doesn't always exist in a profile's field

Those changes make the absence of the first less verbose (instead of logging the exception inside the ui and mucking up the whole display, only the "Press X to view" is displayed) and the absence of the second one not crash

Thanks for this tool !
