Allow inactive financial types to be selected for eligible configuration
The setting screen for which financial types are eligible for GiftAid only allows selecting active financial types.
A problem arises when:
- recur is set up with type A, which is configured as eligible.
- at a later date, the charity stops using type A, and disables it
- contributions come in for the recur (1) but type A is no longer eligible.
Whether (3) has impact will depend on whether anyone has used the UI or not; using the UI after (2) will cause data loss.
This PR corrects that by listing all financial types in the UI.
