Ungit triggers heroku rate limiting

[ylecuyer]

When using ungit with heroku remotes it often triggers the rate limiting.

I'm not sure if it is because I have two heroku remotes and calls are made at the same times to the two remotes or if ungit do too much requests to heroku when updating.

remote: !	Your account reached the API rate limit Please wait a few minutes before making new requests
fatal: unable to access 'https://git.heroku.com/project.git/': The requested URL returned error: 429
