Fix `NetServerTurnManager` from pausing the simulation forever after a
client sent a bad hash to it and disconnects before the bad hash has
been processed.
A client that sends a wrong simulation hash to the `NetServer` and
disconnects before the server compares that hash causes a message box to
appear and the game to be paused forever.
94e5d88169 introduced the bug by missing to delete `m_ClientStateHashes
upon `UninitialiseClient.
This causes `m_ClientData[hashPair.first].isOOS = true` to insert a
client with blank values that the `NetServerTurnManager` will wait
forever and hence the message box about an OOS with no players being OOS
is shown (the playername is emptystring).
5ebf2020b0 exposed the bug by making observers able to lag behind,
providing a longe enough timeframe for this to occur.
Fix:
Deleting `m_ClientStateHashes` upon disconnect solves the broken
message box and the pausing.
