The new test `typeMismatch.lean` contains two examples where the error
message was dreadful.

2f4340f63c feat: refine refine tactic 
Now `refine stx` reports an error when there are natural unassigned
metavariables after we elaborate syntax `stx`. The idea is that only
synthetic holes `?<hole-name>` become new goals.
The tactic `refine! stx` implements the Lean3 behavior.
