When encountering multiple available same named types,
resolve all of them together with corresponding extensions.
This aligns well with the current resolve behavior of classes
with the same name (see `SameNameClassesFromStarImports.kt`)
Also, add extra test for resolving the ambiguous type without
the extension function. The behavior is the same - resolve to the
both classes.
