A weboob contributor proposed a patch to fix the Date when empty:

"For the field date, the module use the column "Date de réception"
and "Date de valeur" if the first is empty. But Spirica uses "-" when
the cell is empty, so no date is returned and boobank uses today's date
as default value."

I adapted his merge request since we now use CleanText instead of
TableCell for iter_history, with the connection I have the symbols='-'
does not change any date but maybe in some cases it will prevent boobank
from returning today's date by default.

Several elements have changed on the Spirica website:
- the "Tout afficher" button disappeared,
- the forms to get the transactions list were modified,
- the forms to get investments for each transaction changed.
This patch corrects history for each account as well as the respective
invests.

[spirica] add currency field on the account, changes xpath on the table to make it adaptable to different currencies

Investments with type 'Fonds en euros' don't have PRM.

Closes: 500979@redmine

Closes: 477593@redmine

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

It doesn't seem easy to quote in xpath, so do a plain-old for-loop.

The investements were simply not returned
