Unit Test Cleanup (#141)

Browse Source 
This is a fairly large set of changes to the unit tests that help isolate the effectiveness of the unit tests.

* Unit tests for query execution have been split into separate files for different classes.
* Unit tests have been added for the ResultSet class which previously did not have tests
* The InMemoryStreamWrapper has been improved to share memory, creating a simulated filesystem
* Creating a mock ConnectionService to decrease noisy exceptions and prevent "row stealing". Unfortunately this lowers code coverage. However, since the tests that touched the connection service were not really testing it, this helps keep us honest. But it will require adding more unit tests for connection service.
* Standardizing the await mechanism for query execution
* Cleaning up the mechanism for getting WorkspaceService mocks and mock FileStreamFactories

* Refactor the query execution tests into their own files

* Removing tests from ExecuteTests.cs that were moved to separate files

* Adding tests for ResultSet class

* Adding test for the FOR XML/JSON component of the resultset class

* Setting up shared storage between file stream readers/writers

* Standardizing on Workspace mocking, awaiting execution completion

* Adding comment for ResultSet class
