After c4a87b34, CapBank has been
backported in modules along with an iter_resources method which does not
take the correct Account class, and thus all modules list no accounts.

Closes: 3271@zendesk

Specify which caps to use will prevent the backend from being used if
the method doesn't exist

update CapBank into CapbankWealth when iter_investments is implemented
update CapBank into CapbankPockets when iter_pockets is implemented
add CapBankWealth when iter_investments is implemented and inherit CapCgp or CapBankTransfer or CapBankTransferAddRecipient
add CapBankPockets when iter_pockets is implemented and inherit CapCgp or CapBankTransfer or CapBankTransferAddRecipient
