Changes

Not 100% sure why we were doing this before, but as of
git/git@9081a42
this is causing Git to return this error when trying to call git checkout -f FETCH_HEAD:

BUG: builtin/checkout.c:1102: should be able to skip past 'refs/heads/' in 'refs/remotes/origin/HEAD'!

IIUC, the symbolic-ref command isn't necessary so we can safely remove
it. Local HEAD will be set on the final git checkout call.

New command flow:

[git init /tmp/git-init-3587814010]
[git remote add origin /tmp/git-init-3399927535]
[git config http.sslVerify false]
[git fetch origin --force ]
[git show -q --pretty=format:%H FETCH_HEAD]
[git checkout -f FETCH_HEAD]

/kind bug

Fixes #4463

/assign @vinamra28 - Would like your review here, since this is undoing changes made in 9aff0a0 and want to double check that I'm not undoing important behavior.

@wlynch, thanks for doing this. At the time of adding the commit 9aff0a0, there were some failures on openshift based clusters but now I guess it is resolved.
