Fix mailbox bootstrap issue

[ghost]

P2P initialization is reverted to the order before #5219 changed it. Then the mailbox initialization is split into a part done before listener modules, and a part after all other initialization is done.

Fixes #5265

---

Details:

TradeManager expects MailboxMessageService to be bootstrapped in order to re-send trade messages at startup, e.g. (CounterCurrencyPaymentStartedMessage). MailboxMessageService implicitly depends on TradeManager to be bootstrapped, because it forwards a dispute message which in turn depends on Trade and TradeManager.

---

The following scenarios are relevant for testing, as are all messages processed or resent at startup.

1. Dispute opened while Bob was offline. (#5210)

• Alice has published a buy offer
• Bob has taken the buy offer
• Alice requests support when Bob is offline
• Bob returns online and the exception is launched

2. With Alice offline, Bob started payment then reboots. (#5265)

• Bob makes offer to buy
• Alice takes offer
• Alice goes offline
• Blockchain confirms
• Bob initiates payment
• Bob shuts down and restarts bisq, then the error message is reported at startup.
