Fix issue 7301 - broken vhost link

[MarcialRosales]

The root cause is that the templates that renders permissions and topic permissions within the vhost page assumes that the users attribute has a paged list of users (i.e. wrapped around an items attribute) however the attribute is just a plain array.

Proposed Changes

Modified the affected templates to list users assuming they are just a plain array rather than an array under items.
Added selenium tests.

thanks for the fix! could this be backported to 3.10.x as well?

[michaelklishin]

Automatic backport to v3.10.x introduces other regressions and had to be reverted.

Backporting this to v3.10.x would have to be manual.

thanks for the manual effort
