Is your feature request related to a problem? Please describe.
If pre-commit modifies a file, such as code formatting, the lazygit interface reloads, but staging the modified file and committing again requires retyping the commit message.

Specifically this happens with github.com/psf/black plugin, but I guess the issue will apply to any hook that modifies a file and reports a failure.

Describe the solution you'd like
It would be good if the commit message was retained in this scenario - so you can quickly stage the reformatted file

Describe alternatives you've considered
None.
