Don't use Markdown cache for stubbed settings in specs

The ApplicationSetting model uses the CacheMarkdownField concern, which updates
the cached HTML when the field is updated in the database. However, in specs,
when we want to test conditions using ApplicationSetting, we stub it, because
this is accessed in different ways throughout the application.

This means that if a spec runs that caches one of the Markdown fields, and a
later spec uses `stub_application_setting` to set the raw value of that field,
the cached value was still the original one. We can work around this by ignoring
the Markdown cache in contexts where we're using `stub_application_setting`.

We could be smarter, and only do this on the Markdown fields of the model, but
this is probably fine.
