[hooks/syncschema] do not crash on double removal of a constraint
Some complicated migrations may entail a double constraint removal.
It is not yet known whether this is a genuine cw bug or the result
of a complicated migration story, but we should nevertheless
not crash.
Rather, emit a CRITICAL warning and proceed.
Closes #3595309.
