Subject: [PATCH] Fix proof-of-burn signing for password protected wallets

Add a missing bsqWalletService.isEncrypted() check and optional AES key
argument to the signMessage(..) call in ProofOfBurnService, analogous to
the BitcoinJ call to sign with an EC key in MyBlindVoteListService.

This fixes #3836.
