refactor(core-transactions): remove custom wallet repository

[rainydio]

Summary

Custom wallet repository was pool isolation technique that was replaced back in March. Since then customWalletRepository wasn't passed into handlers, but handlers weren't updated to remove unnecessary parameter. All mentions of customWalletRepository are now removed making handlers slightly more straightforward.
