hotfix-finish: plugin fails when remote already up to date

[Steph0]

Hello,
First of all, thanks for this amazing pluging
I come across a very strange case where the plugin fails for a reason that does not seem right.

What happens is that for some reason, 'master' and 'dev' are already merged.
I would expect not to fail and just continue (and updating the version in snapshot for example).

Note: same error in version 1.16.0 of this roject

Thanks for your help!

It would be nice to have this controlled by some parameter, but then we need to check diff or dry-run it first.

Is there any workaround for this bug?

Same problem for release-finish. Is there any update? Thx!
