[FIX] hr_expense: Correct states are used in the payment_mode field

The states for the expense are:
- draft
- reported
- approved
- done
- refused

So in the definition of the `payment_mode` field, these states must be used.

Before this fix, wrong states were used in the definition of the field
`payment_mode`.
