generator-jhipster-53 http-auth-interceptor does not work correctly

Julien,

I fixed the both problems. 

I changed the gzipFilter because I didn't find why when the files (css or scripts) are concatenated the filter returns no data. Now it works.

I also found an option on the http-auth-interceptor which allows to bypass the HTTP 401 error. Check the ignoreAuthModule option in the code.
