Hannah Wolfe cd3f8e9e2d Reordered routes to load taxonomies last
closes #11936

- the driving reason for doing this is so that when posts and taxonomies all have the same route,
  e.g. /:slug/ the /edit route won't default to looking up tags
  this is the issue outlined in #11936
- the side effect of this is that in this case, all routes will default to looking up posts before tags,
  so if you have a /test/ post and a /test/ tag, prior to this change, the tag would have been loaded first
  but posts are more important than tags, and should have higher priority, so this change is considered correct
