[FIX] account: frequent tax undeterministic result

- Create a db with account installed (and a random loca)
- Run the test "test_quick_edit_total_amount"
=> The test may fail (undeterministically), especially the first time

The reason is that we don't have an order in "_get_frequent_account_and_taxes"
So, if we have the same number of lines with the same account and with a tax or without one,
we can not guarantee which tax is considered the most frequent.

We now define the order by saying that we should take the taxes into account,
so lines with taxes take precedence on lines without
