"full message view" not needed because of footers

standard footers meanwhile go the "contact status",
so they are no longer a reason to trigger "full message view".

this was already discussed when the HTML view was introduced at #2125
however, forgotten to change when the "contact status" was added at #2218

this pr will result in a cleaner chat view
with less "Show Full Message..." buttons
and will also save some storage
(in fact, i came over that when reviewing #4129 )
