[Sprint/LuckyLizard](fix): Moved nsfw entity/attachment propegation so it executes.

If this is set before execution of $attachment->setNsfw($activity->getNsfw());

Then the activity->getNsfw() returns null, and thus it isn't set.

Both of these occurrences appear to be unneeded as the change works.

Note

I am not able to discern why this was called twice to start with, so this will need thorough testing.
