Search code pagination is slow/broken

[ericholscher]

The default count method on our ES "querysets" is really slow

We have worked around this by exploiting a behavior in Django that just calls len(queryset) when count() is invalid.

We should fix this in a better way, so this ticket exists to track that work.

@ericholscher Is this still valid with the new search?

[ericholscher]

Yea, I believe we removed the workaround. There is still another issue with counting in #5235, but we can close this.
