$this->conn_id BOOLEAN(FALSE) instead of mysqli link

Actually I've found somewhere in my old test methods the line loading session library which explains why ci_session table was instantly checked.

Still I can't make $this->conn_id work after disabling one or the other - using the database for session or loading the session from that hidden line.

I'm using CI version 2.1.0
