Bot submits Homebrew PRs on the wrong base

[code-asher]

I think it might be because brew bump-formula-pr is basing it off cdrci's fork which is outdated. Perhaps there is a flag to pull the latest changes into the fork first or maybe we'll have to do it before running brew.

Notes

The way this currently works is we use brew bump-formula-pr using @cdrci's GitHub Token (environment variable).
The docs for brew bump-formula-pr: https://github.com/Homebrew/brew/blob/master/Library/Homebrew/dev-cmd/bump-formula-pr.rb#L18

This is because cdrci/homebrew it out of date, right? So why don't we just add some commands to the script:

• checkout cdr/hombrew
• pull remote changes
• update fork
• run brew bump-formula step

This could work.
