Fix email invites address-match checking
Riot was always saying the email address that the invite was sent
to was not associated with your account.
Two fixes here:
1. We mounted RoomPreviewBar with no invitedEmail prop and then
changed the prop later, but RoomPreviewBar only checked for it
on mount. Make sure we re-check when the props change.
2. Pass oobData through RoomPreviewBar because we need to pass it
to the RoomAvatar for 3pid invites.
