sw: fix use-after-free in SwAccessibleMap::FireEvents()
As seen when running JunitTest_sw_unoapi_3 against "make debugrun",
the damn thing can call itself recursively via an odd corner case in
GetContext():

Presumably all of mpEvents, mpEventMap and mpShapes must live until
the outermost FireEvents() completes.
