• Remove redundant code, add some unti tests

Abandoned in favour of https://git.kolab.org/D1408.

• Limit alias duplicates to private domains

• Small code improvements

• Use YYYY-MM format in receipt filename

@vanmeeuwen, I rebased, fixed obvious bugs and refactored the code so now we have Wallet::balanceLastsUntil() that we need tests for in tests/Feature/WalletTest::testBalanceLastsUntil().

• Fix error due to missing use statements
• Create Wallet::balanceLastsUntil()

This learned us that an exception does not rollback uncommitted transactions. Here's a general fix for this issue:

--- a/src/app/Exceptions/Handler.php
+++ b/src/app/Exceptions/Handler.php
@@ -5,6 +5,7 @@ namespace App\Exceptions;
 use Exception;
 use Illuminate\Auth\AuthenticationException;
 use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
+use Illuminate\Support\Facades\DB;

My comments to src/app/Domain.php were not addressed, but it's not critical.
