fix(rooms): "Rename for me" names in search results, inbox and threads (#336)

Follow-up to #359: the personal room name now also shows in message-search
result groups and the search room filter (whose room search matches it
too), Inbox → Notifications, the threads list and the thread panel header.

Verified headless with general renamed to "Zebra Lounge": a global message
search and Inbox → Notifications both show "Zebra Lounge".

Fixes #336
