Order of FILTER placement and FILTER equality transformation can be sub-optimal.

In Jena 2.11.0, the equality transform is done before the filter placement.

This order of applying these two optimizations is not optimal if the filter placement enables the equality transform where it was not going to be applied before.

JENA-595 pushes filter placement more deeply inside compound patterns so it is possible that the filter now applies to a smaller pattern where the equality transform is now valid.
