Don't pull updates for repositories marked as hosted

Summary:
  - Don't try to pull hosted repos.
  - Also, fix the `--verbose` + `--trace` interaction for `bin/repository`.
  - Also, fix a couple of unit tests which got tweaked earlier.

Test Plan:
  $ ./bin/repository pull GTEST --verbose
  Pulling 'GTEST'...
  Repository "GTEST" is hosted, so Phabricator does not pull updates for it.
  Done.
