Bitbucket Server importer: Eliminate most idle-in-transaction issues

Just like with the GitHub importer, the Bitbucket Server importer can hit the
default 60 s idle-in-transaction timeouts if it takes too long to create the
merge request. We solve this by using the same approach as the GitHub importer:

1. Bypass all validation and hooks in creating a merge request
2. Insert the Git data in a separate transaction

When using ruby interpolation in externalized strings, they can't be
detected. Which means they will never be presented to be translated.

To mix variables into translations we need to use `sprintf`
instead.

Instead of:

    _("Hello #{subject}")

Use:

    _("Hello %{subject}) % { subject: 'world' }
