Divide Conversation into ConversationInfos, ConversationMember, and ConversationSummary

- ConversationSummary is used to display ConversationList.
- Having the three separated will help managing queries.
- Adding ConversationSummary required to solve some inconsistencies in ConversationList, which was mixing contacts and conversations. ContactSearchResultList has been added as a quick fix . It will need more work.
- Some tools to uniformize conversation names have been introduced. They will need more work.

Note the diplaying of ConversationList is left broken in this commit.
