Why do PropertyAssignments need to be filtered out?

Also nit: these ifs can be collapsed into one.

Duplicate comments were being emitted before filtering out PropertyAssignments. I believe PropertyAssignment comments are already being emitted by emit(child), which is why it would make sense to filter here. But it does feel like a workaround, and I'm new to the TypeScript codebase so I'm unsure of a more correct way to go about this is.

And thanks for the suggestion on the if-statements, I will fix that shortly.

@rbuckton will likely have a suggestion about whether there’s a better place for this to go where it wouldn’t have to filter like this, or maybe a better condition to filter by. I’m not very familiar with comment emit myself.
