Revert molinillo bump

Remove duplicate framework names

 A "host target" (Eg: iOS app target) aggregates all "pod targets"
 for an "embeddable target" (Eg: extension). When app and extension
 use parts of a pod via sub-spec, the "pod target" names are unique,
 but module_name is specified only at the root_spec. The target
 validation should consider only unique module_names while detecting
 duplicate frameworks.
