af5019c8dd SSU2: Fixes part 11
Save data messages received before or immediately after session confirmed
by queueing them for processing after the PeerState2 is created.
The fragments for the first I2NP message from Alice to Bob are frequently lost,
this will hopefully fix it.
Not fully tested, needs wider network testing.

9457271ce6 Transport: Fix wasUnreachable() for transports with alt style
Only affects NTCP for now.
