phabricator: do not read a same revision twice

It's possible to set up non-linear dependencies in Phabricator like:

  o   D4
  |\
  | o D3
  | |
  o | D2
  |/
  o   D1

The old `phabread` code will print D1 twice. This patch adds de-duplication
to prevent that.

Test Plan:
Construct the above dependencies in a Phabricator test instance and make
sure the old code prints D1 twice while the new code won't.
