LUCENE-7657: Fixed potential memory leak when a (Span)TermQuery that wraps a
TermContext is cached.
> Queries that reference a TermContext can cause a memory leak when they are
> cached

> The {{TermContext}} class has a reference to the top reader context of the
> IndexReader that was used to build it. So if you build a {{(Span)TermQuery}}
> that references a {{TermContext}} and this query gets cached, then it will
> keep holding a reference to the index reader, even after the latter gets
> closed.
