This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
The instagram onebox sometimes surrounds the image with an `<a>` tag, which was breaking the aspect ratio logic, and therefore causing posts to change height on load.

Featuring topics for `list/categories` is a very expensive operation that
happened each time we created a topic. This introduces a test only bypass
We found the previous triggers less straight forward than just calling
it tutorial.
`start new user` -> `start tutorial`
`start new advanced user` -> `start advanced tutorial`
This is a feature that used to be present in discourse-assign but is
much easier to implement in core. It also allows a topic to be assigned
without it claiming for review and vice versa and allows it to work with
category group reviewers.
If creating a topic via the api as an admin and the category you specify
cannot be found an error will now be returned instead of just creating
the topic with no category. This will prevent accidental public topic
creation originally intended for a private category.
This commit is follow up to 535c594891 and
still allows for the creation of topics where the category param is
blank.

`#find` raises an error if the id given to it is invalid. As a result,
the conditional to check whether a `group` or `badge` is `present?` will
not be executed if any of the ids are invalid.
