Need to rework Pester tests to test against static content

[sdwheeler]

The current Pester tests use fixed strings for comparison of MAML content. But the build process does an Update-Help first. Since the help content has been changed in the past two years, the tests fail.

We need to create new test content in the test folder that can be used instead of using Update-Help. Also, I believe there is some duplication of tests between the two scripts.
