git CRLF config is breaking unit tests

[jefflill]

It looks like we have git configured for our repos to convert CRLF in source code to just LF. This is causing problems for unit tests that using verbatim string literals that assume that these strings will use CRLF for new lines. This is also discussed here:

I've been also seeing build warnings saying that LFs will be converted into CRLFs for months now, which is probably related. I think @marcusbooyah must have changed the checkout policy a while ago.

We could reset this policy to CRLF locally but I don't want to go there right now. I'm going to modify the tests to ignore CR characters when present instead.

I fixed these tests by using TestHelper.AssertEqualLines() instead of Assert.Equal()
