Undercloud: fix stackrc TLS URL detection
Undercloud: fix stackrc TLS URL detection

We want to configure a TLS url for the underclouds stackrc
when a user specified or generated TLS certificate is used.
This patch updates the existing check so that
the PublicSSLCertificateAutogenerated paremeter is also used
when deciding if the SSL URL should be enabled.
