Pre-commit hook does not check test pass/failure before allowing commit ...

I'm trying to debug why a test is not passing for #35
and when I attempt to make a commit on my branch (_where tests are failing_)
I am not _prevented_ from doing so ...


`pre_commit` is in the `mix.exs` file:
https://github.com/dwyl/github-backup/blob/9aec5c46b47922ea0cfd4c486008d0fb44b1248a/mix.exs#L50
But it's _unclear_ what command is being _run_ on the pre-commit hook ...

https://github.com/dwyl/github-backup/blob/5033458e0385a927faa7efb5cdb97584bf87d901/config/prod.exs#L34-L35

Why is the `pre-commit` defined in `prod.exs` ?

It would be _desirable_ to have the `pre-commit` run on `localhost` i.e. `dev.exs` ...
@SimonLab / @Cleop thoughts...?
