The user page datagrid unit tests now utilize the new expected query

helper functions to build more maintainable sets of query expectations

that the datagrid's queries can be tested against.
All tests now go through one of two helpers:


_build_user_review_requests_datagrid_equeries(), which manages the

   review requests part of the user page.


_build_user_reviews_datagrid_equeries(), which manages the reviews

   part of the user page.


These build all the datagrid query assertions, utilizing these helpers

and the arguments provided to test both datagrids. It's now much easier

to determine how the tests differ and to keep them maintainable as work

on the queries continues.

Unit tests pass.
