fix(core-magistrate): use wallet publicKey for business id index

[air1one]

Summary

Resolves #3259

Use wallet publicKey for business id index, as a business is unique to a wallet.

Before we were using a wallet manager based index which can lead to bugs (database wallet manager does not hold the same state as tx pool wallet manager, so we can easily choose a wrong id).
