auto-t: add DPP tests to check extra settings are applied

In order to test that extra settings are applied prior to connecting
two tests were added for hidden networks as well as one testing if
there is already an existing profile after DPP.

The reason hidden networks were used was due to the requirement of
the "Hidden" settings in the profile. If this setting doesn't get
sync'ed to disk the connection will fail.
