Default auto commit confirm to "true".

[jonpugh]

I'd like to automate the composer update auto commits, but currently it skips committing when using the --non-interactive option.

I almost always want to commit when running interactively as well.

For both of these reasons, I think it's nice to default the confirmation to commit to "yes".
