LanguageExclude values specified by parameter behave differently from values set in the config file.

[jlaanstra]

LanguageExclude values set in the config file will cause PDP info to be excluded but the languages will still be listed in the json output.

LanguageExclude values passed as a parameter to New-SubmissionPackage will be ignored and override the config file and result in the languages as well as PDP being included in the json output.
