The Dashboard 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 a _build_datagrid_equeries(), which manages

all the datagrid query assertions, utilizing these helpers and the

arguments provided to test all view modes of the datagrid, including

sidebar functionality and all available columns.
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.
