Resolves#4094
## Description:
In Free-For-All (FFA) mode where teams default to 0, player isOnSameTeam
checks returned false for oneself, allowing players to attack
themselves. Consequently, if a bot conquered the targeted tile between
queueing a transport ship action and its actual initialization, the
target became itself, causing the bot to execute a self-invasion.
This fix adds a reflexive check in PlayerImpl.ts's isFriendly method to
always treat oneself as friendly. It also adds a safety guard in
TransportShipExecution.ts's init method to abort ship execution if the
target has shifted to the attacker.
