client/transaction search: the "select all" checkbox is always checked at the opposite of what is expecteed
if some of the categories are not selected, the "select all" checkbox is checked.
if all the categories are selected, the "select all" checkbox is not.
The problem is here : https://framagit.org/kresusapp/kresus/-/blob/master/client/components/ui/multiple-select.tsx#L40
There is a
! which should not be there.
