Description
I ran odasa qltest on a test directory in which I'd neglected to include any source files.
Expected: The extractor should fail with a message like "There are no source files in this test directory."
Actual: The extractor fails with a null pointer exception.
[1/3] Extraction failed in D:\dev\codeql-2\msft\cpp\ql\test\query-tests\Maintainability\CopyrightNoticeCommentsExpertise (extraction: 175ms)

Let me know if this isn't the right repo to file this in.
