Comment on catchIlltypedPatternBlockedOnMeta needs update

[andreasabel]

@UlfNorell, please have a look at this comment and update it to the current situation:

agda/src/full/Agda/TypeChecking/Rules/Term.hs

Lines 824 to 827 in 5d25cf8

	-- Note that the returned meta might only exists in the state where the error was
	-- thrown, thus, be an invalid 'MetaId' in the current state.
	--
	catchIlltypedPatternBlockedOnMeta :: TCM a -> ((TCErr, Blocker) -> TCM a) -> TCM a

• There is no more meta returned or passed to the continuation. Instead, there is a Blocker.
• Does the comment still apply to the blocker?

Doesn't make sense to raise these kind of issues if folks do not take responsibility.
