Message "You have been redirected ..." not seen when it occurs

[izmeez]

This was previously mentioned in #25 as a side issue.

When on a subdomain go to /admin/structure/domains and edit one of the domains. User is redirected to the primary domain but does not see the message they have been redirected. Only when user goes back to the subdomain, with the browser back button, and flushes caches the message is displayed, You have been redirected: This page must be accessed from the primary domain. This message seems out of place. It probably should appear on the primary domain when user is redirected.

@izmeez I can recreate this issue and am trying to solve this issue but I think, In Backdrop CMS messages set with backdrop_set_message() are stored in the session, which means they should persist across requests, including redirects within the same domain. However, when redirecting to another domain, Backdrop doesn’t automatically share session data across domains, so the messages may not be available on the primary domain after a cross-domain redirect.

Interestingly, after the domain_theme module is enabled this behaves as expected. The message You have been redirected: This page must be accessed from the primary domain. shows on the primary domain after the redirect has occurred.

Should note that I did login to the primary domain prior to visiting the subdomain and as an administrator, so the correct behaviour may have nothing to do with enabling domain_theme and be related to the session.

@izmeez I have domain_theme module already enabled but in my case, it didn't work.

How silly of me, it has nothing to do with domain_theme. The fix has to do with #39 and the PR #46 that I had applied.
