Add test for Custom Server Hooks on Create Tag API Endpoint

Server admins have the ability to define GL-HOOK-ERR to present a
custom message to clients when a commit is declined or when an
error occurs during the Git commit.
This test verifies that these erorrs are presented on the API level
via testing the create tag API.
