K2: do not try to resolve invoke on error receiver

Browse Source 
If a potential receiver is resolved to an error type, we consider
any other type as a subtype of it and therefore may select
any candidate that we happen to find in a scope.
In particular, in the case of scripts, or code with a context receiver,
the receiver candidate resolved to a cycle was accepted as a receiver
to an invoke on a random class from stdlib.
The fix skips adding invoke resolve task in this case, allowing
the tower to find the correct candidate in another scope.

#KT-64241 fixed
#KT-65576 fixed
