[PATCH 6/6 v5] revert.c: delegate handling of "-" shorthand to setup_revisions

[Siddharth Kannan <kannan.siddharth12@gmail.com>]

revert.c:run_sequencer calls setup_revisions right after replacing "-" with
"@{-1}" for this shorthand. A previous patch taught setup_revisions to handle
this shorthand by doing the required replacement inside revision.c:get_sha1_1.

Hence, the code here is redundant and has been removed.

This patch also adds a test to check that revert recognizes the "-" shorthand.
