Cannot remove Wikibase entity alias #123
Description
Trying to remove an alias from a Wikibase entity does nothing. The problem seems to be that WikiClientLibrary.Wikibase.Entity.SerializeEditEntries does not fill Contracts.MonolingualText.Value when removing an alias. While for Labels and Descriptions this is fine (those are WbMonolingualTextCollection – the language uniquely identifies the label/description to be removed), for Aliases this does not work (it is a WbMonolingualTextsCollection, and the language identifies a set of aliases, and the specific alias to be removed needs to be specified.
