Instead of displaying 'invert' when looking at some events like MP_FAIL,
MP_FASTCLOSE, MP_RESET, RM_ADDR, which is a bit vague because they are
not traditionnaly sent from one side, the host being checked is now
printed.

For the ADD_ADDR, only display the host when it is the client sending
it, which is more unusual.

Also before, the 'invert' message was printed after a few checks, but it
was not clear which ones exactly.
