mungegithub misbehaves when github returns 502s

[eparis]

Likely a problem because the 'branch name' helper does not return an error, so the munger worked with "" instead of realizing there was an error. The helper was originally intended to check the positive, but was used to check the negative, in which case the distinction of 'error' is important. There are probably other helpers that really should return an error code :-(
