Fix pull-replication update head with Gerrit replica
I2211201f2 introduced the support for Gerrit replica
but all the tests were run against Gerrit primary with
the native REST-API, instead of using the pull-replication
plugin specific API executed through a filter.
The combination with Gerrit Issue 290794206 made
the bug invisible because all UpdateHeadActionIT tests
on replicas were still passing, because the underlying
Gerrit daemon was still a primary even if the test was
configured with container.replica = true.
Fix the implementation of the update head functionality
on Gerrit replicas and amend the validation tests for
making sure that it won't break again in the future.
