Add a safety check to commit discovery daemon

Browse source 
Summary:
Although I couldn't repro the issue in T692, I did manage to point the "Diviner"
repository at the "Phabricator" working copy and screw some stuff up on
secure.phabricator.com.

Before discovering commits in a repository, ensure the 'origin' remote points at
the configured URI. This prevents issues where the working copy gets configured
to point at an existing (but incorrect) checkout.

Test Plan:
  - Ran gitcommitdiscovery daemon normally under "phd debug", saw it execute the
"remote show -n" command and then start working.
  - Intentionally botched the config, got an exception:

  (Exception) Working copy '/INSECURE/repos/phabricator' has origin URL
  'ssh://git@github.com/facebook/phabricator.git', but the configured URL
  'git://github.com/facebook/diviner.git' is expected. Refusing to proceed.
