phabricator: make user searches case-insensitive

User names in conduit are case insensitive, but when looking for "FOO"
it would return "foo" instead and we'd think the user didn't exist.  So
lower case both the query and the response when comparing them.

Do not crash with empty repo:

  $ hg absorb
  abort: no mutable changeset to change
  [255]

Make some commits:

  $ for i in 1 2 3 4 5; do
  >   echo $i >> a
  >   hg commit -A a -m "commit $i" -q
  > done

  $ hg annotate a

Change a few lines:

  $ cat > a <<EOF
