[compiler] Don't show hint about ref-like naming if we infer another type (#34521)

Some components accept a union of a ref callback function or ref object.
In this case we may infer the type as a function due to the presence of
invoking the ref callback function. In that case, we currently report a
"Hint: name `fooRef` as "ref" or with a "-Ref" suffix..." even though
the variable is already named appropriately — the problem is that we
inferred a non-ref type. So here we check the type and don't report this
hint if we inferred another type.
