[FIX] web: fix various bugs in FieldCharDomain

now, the FieldCharDomain widget should
* correctly display the selected records instead of the whole list
* allow the removal of the current selection in edit mode (by adding
  a facet in the searchview)
* allow the selection of a full group when the list view is grouped

also, it correctly now uses the ReinitializeFieldMixin instead of
reimplementing half of it in a buggy way.
