When trying to onebox topics, the canonical URL overrides the generated
OpenGraph tags, causing a less than ideal onebox for a linked KE
article.
This commit uses the existing options for the `crawlable_meta_data`
method to generate the `og:ignore_canonical` tag.

Logic was not properly checking if there was a topic selected or not. As a result, the template for onebox data was still being loaded, causing an error. Also changed the order around TopicView to avoid unwanted effects.
Currently linking directly to Knowledge Explorer topics shows a generic onebox, which isn't super helpful in some cases.
This commit mimics how the theme creator plugin handles adding metadata to special occurrences. However, to get this to work, how the plugin handles showing topic contents needed to be refactored. Instead of hitting the existing topic route, the plugin implements its own version of this, including adding restrictions for topics that are not in a selected Knowledge Explorer category or tag.
