Add directory structure tests for SAST analyzer nodejs-scan
The nodejs-scan MR Update to Babel 7.7.0 upgraded the analyzer to use Babel 7. Unfortunately Babel 7 no longer maintains that the same directory tree input will be output in the same locations. Which may have implications on files named the same, but in different directories. The MR made sure to use Babel in a way that made sure to maintain the same directory tree on output. We should also add tests to show that the directory tree is preserved.
