Make CreateGpgSignatureWorker backwards compatible with original method signature (CE port)

See merge request gitlab-org/gitlab-ce!20998

Older versions of GitPushService push a single commit SHA string to the queue,
but Gitaly requires that the parameters sent by CreateGpgSignatureWorker are
an array. It's possible to have old workers using this original signature or
jobs in the retry queue that would fail if CreateGpgSignatureWorker can't
handle the string form.
