`INVISIBLE_REFERENCE` may be reported due to CandidateApplicability via
a ConeDiagnostic, or in a checker. The former leads to
`FirErrorResolvedQualifier`, so the checker is not called.
This makes little sense, because CandidateApplicability may result in
`NO_COMPANION_OBJECT`, which would prevent other more meaningful
diagnostics from being reported (like `API_NOT_AVAILABLE`).
If we run checkers for `FirErrorResolvedQualifier` we may get duplicate
`INVISIBLE_REFERENCE`. The change in the checker prevents it.
Callable symbols with SinceKotlin are filtered out by a
resolution stage, but in K1 classifiers and property accessors
report API_NOT_AVAILABLE. K2 filters out properties with
unavailable accessors, but does nothing for classifiers.
This change fixes it.
