[FIX] hr_expense: Fix payment method line flow

The payment method line set on the expense sheet isn't the one used
on the payment.

The 'print check' payment method test, requiring
the 'account_check_printing' installation and that module not being
in hr_expense dependencies would fail if both weren't installed.

A new and more method-agnostic test replaces it
