[#3819][7.50] Erlking: Boarding entirely OOS results in voice lines being out of date

[Fluggonaut]

Steps to reproduce

1. Board the VIG Erlking entirely in low attention.
2. Get the Erlking out of there and get ready to meet it. This savegame is in exactly this situation.
3. Fly towards the Erlking in front of the player.

Expected result
The voice lines that come up reflect the situation (Erlking has been boarded) in some way.

Actual result
The voice lines roughly go as follows:

1. AI: Odd energy signature detected
2. Boso Ta: Nice ship, unorthodox power supply, not yet complete
3. Boso Ta: If it was complete, few could stand against it in direct combat
4. Boso Ta: How about a boarding operation?
5. VIG: Get off my lawn, consequences, bla bla
6. VIG: Shoot down that ship

As you can see, the last two parts are out of date. A very quick fix would be to cut it off at 3. in case the player already owns the ship and call it a day.

Speaking of which, boarding the Erlking entirely OOS feels a bit too easy.
