Update templates\samples\tests to use ensure viewstart.cshtml and views directory names are cased appropriately #1559

@pranavkm , could you please review this PR??
Remove this test and instead add two separate tests, One which verifies the value of `ViewLocationFormat` and one which looks at `AreaViewLocationFormat`. All you need to do is check if the value returned by the two is identical to a hardcoded list in the test.
