Language switch URL should consider query params

If you go the following URL in the Jahia demo
http://www.jahia.net/demo5/Jahia/cache/offonce/lang/en/pid/16?entryId=237

Then if you change the language to francais, you will not get the same entry in french, but there will be a page saying "Could not find any entry" in French.

I think that in ProcessingContext.composeLanguageURL you should also append the queryString of the request (that is "entryId=237).
