This fixes a scenario when INVISIBLE_REFERENCE is suppressed, but we
resolved to the wrong overload because when none of the candidates were
applicable, more or less the first one was chosen.
Because we call `fullyProcessCandidate` on the candidates, their
applicability can change which can lead to a situation where the
applicability of a ConeAmbiguityError is different to all its
candidates. The changes in coneDiagnosticToFirDiagnostic.kt account for
that, otherwise code like candidates.first { it.applicability ==
CandidateApplicability.UNSAFE_CALL } can throw NoSuchElementException.
