Steven Hardy f019fb002e Fix some map_replace issues
While testing I discovered a couple of corner cases not previously
handled:
- If you provide values/keys via a get_attr reference it's possible for
them to be None during validation
- If the input map has an unhashable value, it breaks the values replacement
so we need to tolerate a failure to lookup an unhashable key in the values
data.
