Change MessageRenderer to define images directory dynamically 

Since the "file directory" where images are stored is the messageId,
injecting it at class creation is not sufficient anymore with the
addition of conversations (when showing a converation's details
MessageRenderer would be init with conversationId, which is not a valid
image directory and would cause images not to be found).

The directory is now defined using each embedded image `messageId` field
