Fix T74897: VSE animation doesn't work

`seq_free_animdata()` removes fcurve pointers belonging to strips from
`Scene` CoW datablock's `AnimData` during `BKE_scene_graph_update_for_newframe`.
This causes problems with updating animation.

This worked before rBbe2e41c397ba, because `AnimData` was freed by `BKE_animdata_free()`
before `seq_free_animdata()` was executed, so it had no data to operate on and returned
on precondition `if (scene->adt == NULL || scene->adt->action == NULL)`
