refactor(linter/plugins): simplify comments getter

[overlookmotel]

Follow-on after #14727.

Since we now have to call into deserializer module to update astId at end of linting a file, we may as well reset the buffers at that point too. This allows simplifying the comments getter.

I haven't looked at other deserializers - I didn't get into them too deep - but this is nice. I like this a lot better.
