Revert "agibbins/dellis: downcase app names in status"

This causes us to output the wrong app name, which
causes confusion, as if you then try to resolve 'merc'
it fails, which is hella confusing.

Any case smashing that is going to be done (and it would be
good if cases were smashed) should be done in deployapp!

This reverts commit 9bf35969b4f087d0dc24185dd60779b3aa53c4e9.
