Fix T45075: "Error, region type 2 missing in - name:"File", id:5"

Unexpectedly found out what was going wrong here. If a file was saved with a filebrowser open, we searched for the channel region in the wrong list (see 'ListBase *regionbase = (sl == sa->spacedata.first) ? &sa->regionbase : &sl->regionbase;').

Minor annoyance is that I had to move the loookup to the 2.77.1 version patch now.
