Change "Copy Room Address" action to "Copy Room Link"

This is way more useful for sharing, as you can use this link in and
outside Matrix rooms. It also matches behavior with other clients like
Element Web.

I also cut some places where this shows unnecessarily, such as direct
chats and invite-only private rooms.
