Description

Another relatedness() bug found in json facet's while working on increased test coverage for SOLR-13132.
if the prefix option is used when doing a terms facet, then the relatedess() calculations can be wrong in some situations – most notably when using limit:-1 but i'm pretty sure the bug also impacts the code paths where the (first) sort (or prelim_sort is computed against the relatedness() values.

Real world impacts of this bug should be relatively low since i can't really think of any practical usecases for using relatedness() in conjunction with prefix
