refactoring for same regression in job versions

In job versions, if you have an ACL token with a write policy
you should be able to revert a job, however, that was not the
case here. This is because we're using ember-can to check if
the user can run a job. That permission relies on policiesSupportRunning
which uses a function called namespaceIncludesCapability. We're going to
need to refactor any cases that use this function.
