MAHOUT-1217: Nearest neighbor searchers sometimes fail to remove points
This fixes FastProjectionSearch's searchFirst() which was not also searching
through pendingAdditions. I think I replicated the bug in the new testRemove()
in SearchSanityTest that now passes. (Revision 1483776)
Result = FAILURE

> Project: Mahout
> Issue Type: Bug
> Components: Math
> Affects Versions: 0.8
> Reporter: Dan Filimon
>
> When updating a Centroid in StreamingKMeans, the Centroid needs to be removed
> and its updated version added.
> When removing points in a searcher that are already there, sometimes the
> searcher fails to return the closest point (the one being searched for)
> causing a RuntimeException.
> This has been observed for TF-IDF vectors with SquaredEuclideanDistance and
> CosineDistance and FastProjectionSearch.
