/**
 * Alters the route for using Taxonomy Views Integrator.
 *
 * Views is allowed to alter and builds the routes first, and we then alter this
 * route after the fact. The idea is so we can have multiple views that define
 * `taxonomy/term/%` as the page path, and the settings form on the term/vocab
 * let the user determine which view displays.
 *
 * Otherwise, Views will always control the path, and that's not what we want.
