test(node): Fix config wizard storage path tests

[teogeb]

Fixed config wizard storage path assertions to be compatible with Mac OS. In the assertion we compare the real path to a symbolic link in Mac OS and thererore the test fails.

Change

Now compares normalized paths, i.e. uses realpathSync which resolves symbolic links.
