> "count all" faceting functionality counts deleted docs for multiple

> A few different {{Facets}} implementations supporting a "count all" style 
> constructor that allows the user to not pass in a {{FacetsCollector}} 
> instance. It advertises that it's equivalent to using a {{FacetsCollector}} 
> populated with a {{MatchAllDocsQuery}}, but more efficient. It looks like, 
> with the exception of {{FastTaxonomyFacetCounts}}, none of the 
> implementations correctly account for deleted documents (have a look at 
> {{FastTaxonomyFacetCounts}} for a correct example that consults "live docs."
> From what I can tell, the affected implementations are:
>  * SortedSetDocValueFacetCounts
>  * ConcurrentSortedSetDocValueFacetCounts
>  * LongValueFacetCounts
>  * StringValueFacetCounts
> I'll attach a PR shortly illustrating unit tests I wrote that confirm the bug.
