fixes bug 36970: Return focus to the record if failed to be edited in grid view

  When a record failed to be edited in grid view right after moving to the form view of its parent record, the window ended in an inconsitent state:
    - The focus was placed at the header
    - The active view still was the child tab

  This was not happening when editing the child record in form view, because the focus was always returned to the form. To fix the problem now the same behavior has been implemented in grid view: in the described scenario the focus is returned to the edit form of the grid.

  Besides, the "editRow" and "editSession" variables were unused in the editFailed() function. Thus, both have been removed.
