615 Run tests through expressions compiled by AssemblyCompiler

• Change CqlToElm unit tests to compile and run via AssemblyCompiler #615

In the CqlToElmTests, the Base.Run(..) method was changed to accept a library as well. This will be passed to Extensions.RunLambda, which takes an AssemblyCompiler on its first param. This new way will run tests through an AssemblyLoadContext which has all the additional fixes in the C# generation step.

This change requires packaging services to be included returned from Base.ServiceCollection(..)

Note, two unit tests failed, which will be ignored and fixed in the next PR #614 . When searching for "[Ignore("Will be fixed in PR 614")]" these are the two tests:

• DataSourceTests.FiltersOnSpecificProp. I'm not sure why, but this test does throw an exception as asserted anymore. Instead it successfully retrieves an array of zero Patients. Is this the intended behavior?
• NotEqualTest.Tuple_Equal_Tuple_Null_Equals_Null

Also, a few other unit tests had to have they cql changed so that it can compile in the AssemblyCompiler. In the cql the The null's were changed to null as Integer:

• InTest.TestInNullBoundaries
• IntervalTest.Interval_Properly_Included_in_Interval_Null
• IntevalTest.Interval_Null_Starts_Interval

⚠️I'm having trouble running the XmlTests through the AssemblyCompiler, so these tests are still compiling the lambdas directly

@ewoutkramer please check DataSourceTests.FiltersOnSpecificProp

• Investigate why DataSourceTests.FiltersOnSpecificProp is no longer throwing exception #621

@baseTwo create separate issue to fix XmlTests

• Change CqlToElm XmlTests to compile and run via AssemblyCompiler #618

It's broken on develop-2.0, it breaks in my totally unrelated branch too 😨
