  parallel sets: fix duplicate navbar on parallel tab reopen (#1366)

When the parallel tab was closed and reopened, navbar_parallel.button_sets
still pointed to the destroyed widget. On recreation, a second button was
added to the new navbar causing a duplicate navigation bar.

Fix: reset navbar_parallel.button_sets to NULL in on_parallel_tab_destroy
so it is properly recreated on next open.
