Fixed (All XF2 Importers) Conversation Master first message / last message info incorrect

[Kier]

Affected version

2.0.1

A bug existed in the XF 2 importers whereby the information written into the 'conversation_master' table regarding the first and last messages in a conversation was in error, resulting in weird read marking, and potentially also the wrong user being attributed as the conversation starter on the wrong date.

This has been fixed for XF 2.0.2
