Don't remember why the previous decision that `Code` and `Release` are
non-disable units globally. Since now every unit include `Code` could be
disabled, maybe we should have a new rule that the repo should have at
least one unit. So any unit could be disabled.

The old code just parses an invalid key to `TypeInvalid` and uses it as
normal, and duplicate keys will be kept.
So this PR will ignore invalid key and log warning and also deduplicate
valid units.
