Pavel Yaskevich f7b264583d [Diagnostic] Don't fix partial mismatch for sub-types associated with optional conversion ...

If mismatch detected by `repairFailures` is related to a complex
wrapped value of optional type formed from optional-to-optional
or value-to-optional conversion let's not try to fix it directly
but let `simplifyRestrictedConstraintImpl` record a top-level fix
for more context.
