Warning during rebase

[dbburgess]

If you make (or amend) any commits during an interactive rebase, you receive the following warning:

fatal: ref HEAD is not a symbolic ref
fit-commit: WARNING: Skipping checks because the Git branch cannot be determined.

Steps to reproduce:

1. git rebase -i HEAD~1
2. Change pick to edit for the commit shown
3. git commit --amend (no need to change anything)
4. Observe the warning.

It doesn't seem to cause any negative side-effects, aside from not actually catching any invalid commit messages.

Thanks for the report and easy steps to recreate.

Since this is a common scenario and not an error case, Fit Commit no longer aborts if the branch name is undetermined.

Awesome, thanks for the fix. It works great. 👍
