Previously, it was failing at line
(resolvedReceiver?.toReference(session) as? FirNamedReferenceWithCandidate)?.candidate?.updateSourcesOfReceivers()
But this line was mostly incorrect because in case of `a.b()` call,
which is resolved to `a.b.invoke()`, `resolvedReceiver` is pointing to
`a` instead of obviously expected `a.b`.
The fix with using `candidate.callInfo.explicitReceiver` doesn't help
either because the candidate of that receiver is always completed at
that stage (so no Candidate there).
The only case when the candidate was still there is PCLA because
in that case we explicitly don't fully complete even receiver
expressions.
(see docs/fir/pcla.md)
The idea of the fix is moving the call of `updateSourcesOfReceivers`
for invoke property receiver to the place just before the candidate
is being converted to the resolved reference
(i.e., the candidate is being lost)
