The space tweaks continue! (#4606)

* Update a string on the space announcement sheet.

* Don't show space rooms after using the join button in the space room list.

* Allow the Deselect All button to Select (almost) All as well.

* Fix the cells in the leave space sheet when there are only admin rooms.
