Fix a few formatting mistakes and remove repetitive method calls

There were a few spots left from #1017 that still needed manual formatting
fixes. And since the method "list" in
OpenQA::WebAPI::Controller::API::V1::JobTemplate and the helper
"current_user" in OpenQA::WebAPI::Plugin::Helpers were affected by this
anyway, i've cleaned them up as well.
