Change current record for the first selected only if there is no current record

#4028 added the behavior to apply the selected record also on form view the
first time.
But when switching to a calendar view from a form view, the tree states is
stored with the current record. If the calendar view is cleared (always with
sao via the search_filter), then the tree_states_done is cleared and on the
second switch to the form view the current record is override by record stored
in the tree states (from the first form switch).

Closes #13939
