Urjent Fix In TextSerch Sorting

When I was playing with changing Java Platform for Compilation I found a bug: HashMap with TextSearch find results was filled in unpredictable way... Which gave different results for JDK8 and JDK7.
That resulted the ruing of tests, and differences to Real Mongodb Text Search result I was re-compared our TextSearch results to.
So I've Made this Changes and Everything is OK now.
Sorry for such a dumb mistake...
