Sara Arjona 734b198fd3 MDL-64715 message: add support for self conversations ...

Added new MESSAGE_CONVERSATION_TYPE_SELF type for self-conversations
and upgraded legacy self-conversations to the new type, removing
repeated members in the message_conversation_members table.
Besides, from now, a self-conversation will be created by default for
all the existing users.

All the self-conversations have been also starred and a default message
will be displayed always to explain how to use them.
