Fixes issue introduced in 7ef482a292
where the correct warning message was not shown when enabling auto-join
for public categories when creating a channel. Adds more system specs
as well to avoid regressions.
When the `navigation_menu` site setting has been set to `sidebar` or
`header dropdown`, overriding the site setting via the `navigation_menu`
query params did not work.

What does this change do?
This commit the client to override the navigation menu setting
configured by the site temporarily based on the value of the
`navigation_menu` query param. The new query param replaces the old
`enable_sidebar` query param.
Why do we need this change?
The motivation here is to allow theme maintainers to quickly preview
what the site will look like with the various navigation menu site
setting.
Allows users to configure their own custom sidebar sections with links withing Discourse instance. Links can be passed as relative path, for example "/tags" or full URL.
Only path is saved in DB, so when Discourse domain is changed, links will be still valid.
Feature is hidden behind SiteSetting.enable_custom_sidebar_sections. This hidden setting determines the group which members have access to this new feature.
The latter can be called directly from the Topic page object,
so we can remove some duplication between the two. There are
levels of page objects (e.g. entire page, component, complete flow)
and its perfectly valid to call one from another.
