[JENKINS-18834] Initial git fetch ignore prune settings

In current release version prune works after fetch. (yeah, I saw this bugfix https://issues.jenkins-ci.org/browse/JENKINS-10348)

But here the bad situation:

1) Create "abc" branch in git repo.

2) Build this branch by Jenkins.

3) Abandon commit and delete branch.

4) Create "abc/asd" branch, trying to build it... and we got a problem.

UPD: my bad, now I see what happens with Prune in refactoring branch. But the problem is still there - Prune executes after fetch, not before it.
