Fix duplication error using MappingStorage

Put MappingStorage over ERP5Storage to map the proper mappings,
by replacing its relative_url IDs with the mapping property.

Change other minor things: sort only by date_ms, not content,
rename author to sender as per the commit before the last commit,
store only the epoch time in milliseconds in messages, not Dates,
and keep only the raw nameToId in id_to_name, not chat-contact-.
