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.
