revset: ensure we have loaded phases data in '_notpublic()'

If we are the very first rev access (or if the phase cache just got
invalidated) the phasesets will be None even if we support the native
computation. So we explicitly trigger a computation if needed.

This was not an issue before because requesting any phase information
would have triggered such computation.
