Don't assume that the last step of the XPath is an element name
In order to find the number of items in the model, the model did a
second query on the document representing the result set.
So, suppose the user queried for //a/b/c, the result set would contain
all the 'c' elements from the input document.
In order to find the number of items in the result set, it did a second
query with the expression "count(/dummy:items/c)", where 'c' was
extracted from the last step in the original XPath expression
For simple expressions, this worked fine.
However, if the last step had a predicate such as "//c/parent::b" it
didn't work.
The solution is to not filter *again* the last step when we query for
the count, since we know that all result items are direct children of
"dummy:items", and instead just execute the query
"count(dummy::items/*)".
This should also potentially improve performance.
