android, desktop: drop changes that do not serve the fix

The connect composer no longer renders in a group's support scope, so no other
view offers to join a prepared group and the record it kept was never read.
Restores the block order in the member contact view, which is in this change
only for the timeout.

Records that the contacts list is not covered, on either platform.
