Clear GtkTreeStore before freeing edt

When building current data for packet details treeview we store two things.
- Generated string with item label
- Pointer to node field_info structure

After epan_dissect_{free, cleanup} pointer to field_info node is no longer
valid so we should clear GtkTreeStore before freeing.
