[FIX] web: Kanban: various bugs in grouped mode

This rev. fixes the next three bugs:
 - the dataPoints representing each group didn't have the parentID
   attribute set
 - when quick creating a record, the res_ids and count attributes
   of the group, and of the parent weren't correctly updated
 - when quick creating a record, the environment (view_manager)
   wasn't correctly updated

The combination of thoses bugs produced the following crash. Open
a grouped kanban view (e.g. project.task), quick create a record,
open that record in form view (note that the pager was wrong, it
indicated 0/x, where x number of records), delete the record ->
the form is supposed to load the next record, but it
crashed because it couldn't get its id (trying to read id null).
