operations: Fix use of wrong config to construct test servers
When costructing test servers via testserver.RunGitalyServer()
, then
registered services should be created with the injected service
dependencies. By accident, we're reusing the Gitaly configuration passed
into runOperationServiceServer()
though instead of the service
dependency one, which may contain configuration which has been changed
by RunGitalyServer()
.
Fix the issue by using the correct config.
