So that we don't have to worry about cleaning empty
directories later. This was brought up at:

https://gitlab.com/gitlab-org/gitlab-ce/issues/38689#note_42242988

Both `Or` and `And` would evaluate whether each rule passed, then calculate a
value based on the results of all of those. We can actually return early in many
cases, without running the rule at all.

The point of this task is to run the import in the foreground, so it
shouldn't schedule an import job!

Since we fetch all the refs we need at the beginning of the import
process, we can safely set this attribute.

MergeRequest#create_merge_request_diff and MergeRequest#reload_diff are
the only places where we generate a new MR diff so that's where we
should fetch the ref.

This also ensures that the ref is not fetched when we call
merge_request.merge_request_diffs.create in
Github::Import#fetch_pull_requests.

The benefit is that we don't even have to create temp source/target
branches.

Also, when the source branch of the imported MR is from a fork, name it
"user:branch" to mimic how we display it for MR when forks actually
exists.

We don't need to check if the existing branch contains a specific SHA
since we only use the branch's name, the SHA is taken from the pull
request raw `sha` data.
