This is very similar to ActivateHome() but will fail if the home directory is not referenced yet. Or in other words, this doesn't add any new reference, but simply is the other side of RefUnrestricted(): if we allowed a home dir to be referenced without it actually being active, then this can catch up with things and activated what was previously referenced already. This also relaxes access rights to that users can always activate their own home dirs. This is useful once we allow user code to run without the home dir being activated.
