Don't panic on unexpected group version for mutated selector
**What this PR does / why we need it**:
`panic` on unknown group version will crash the whole apiserver (even when selector isn't mutated), have a single resource affect the whole cluster, and make debugging harder. ~Return an internal error (i.e. not user error) instead.~ Make "selector immutability" the default behavior instead.
