[hal_json_style] Necessary changes to support Accounting Reports

Search mode of getHateoas now is able to facilitate ListBoxes as well
as Related Fields and Reports. If the search is issued by ListBox's
list_method then the method MUST specify all its input arguments and
do not try to obtain them from REQUEST because it is called asynchronously
from the config form submit thus with different request. It will be supplied
only those parameters specified as input parameters (via introspection).

Changes in Base_callDialogMethod ensures compatible Skin Selection
since the skin change happens there.

getHateoas extends its functionality to render ERP5 Report alongside
with ERP5 Form. It unfortunately creates Selections for Report Section
Form's ListBoxes who uses them instead of input parameters. Those
selection hangs in memory because by the time we need to remove them
we don't have the source Report Section to it anymore.
