Bug fix for parsing required modules when publishing

[alerickson]

PR Summary

RequiredModules were not being parsed correctly from a module manifest during publish time, thus when, for example, RequiredModules contained both a Hashtable and a string, the hashtable would be parsed as a string and incorrectly assume the module name was "System.Collections.Hashtable". This PR loops through every element of RequiredModules and tries to parse each object individually instead of assuming that all types within RequiredModules are the same and attempting to parse the object as a whole.
