Boone Gorges 0bbd0f3a5f Improve category check in redirect_canonical() when permastruct contains category slug.
[37262] changed a check in `redirect_canonical()` so that it checked
categories in the object cache rather than querying the database. However,
the check was based on the identity of `WP_Term` objects, which in
certain cases can be augmented by the main WP query routine, causing
failures of the `in_array()` check. This caused unnecessary redirects
for URLs where `is_single()` is true, but the URL is different from the
post permalink, such as the `embed` endpoint.

`has_term()` also checks the cache, but does not sufer from this bug.

Props cmillerdev.
Fixes #36602.
