The Date() filter raised many issues on Sibi for spirica and the related
modules such as BforBank.
It seems that it's because we need to pass the CleanText() filter to the
TableCell value before applying Date(), with an empty string as default
value, as it is done in Linxea.

This is a blind fix concerning the "symbols = '-'" patch from a weboob
contributor: https://git.weboob.org/weboob/devel/merge_requests/218
It seems that something with the obj_date is causing crashes on the workers that we
cannot reproduce locally so while I am waiting for the session folder,
this fix may reduce bugs on the spirica module.

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: 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.
