[FIR] Fix exception in Java scope caused by inherited member with implicit return type

It's caused by checking the return type of an inherited property.
toConeKotlinTypeProbablyFlexible() returns an error type when the
type ref is unresolved instead of throwing.
This "breaks" some override checks and in the added test, it leads
to an additional candidate being created for a synthetic property.
However, the candidate has applicability K2_SYNTHETIC_RESOLVED
and gets filtered out because the real property has a higher
applicability.
