Fix startup error: "You must have bootstrapped before adding data to the P2P network"

[ghost]

TriggerPriceService is changed to use a BootstrapListener on the P2PService so that it can start after the P2P network is ready.

Fixes #5190 : Prevents an Uncaught Exception error at startup.

---

To test (pre):

1. Create offer Buy, choosing "Deactivate offer if over x" price with a trigger price just above current spot.
2. Close down Bisq and wait for the market price to move over the deactivation price.
3. Start Bisq, the error message above will pop up.

To test (post):

After applying this patch, at step 3 the offer will be deactivated successfully on startup and not produce an error popup.
