[FIX] web: don't allow to aggregate date(time)

Go to Accounting > Accounting > General ledger. The view is grouped
by account. There is a layout issue as the first column (date) is
positionned after the group names, leaving a large blank space.
This is because the date field is considered as an aggregated field
(for sorting purpose, in python), but the JS can't (and we don't
want to) display it. This rev. ensures that such field types are
completely ignored by the JS, s.t. they do not impact the layout.
