Broken View/Edit Routes to Matrix in Admin

All routes to view or edit matrices are incorrectly using the matrix `handle`, rather than the URL-friendly slug used to retrieve entries. For example, if I create a matrix titled 'Book Pages', the link in the admin sidebar to the matrix is `/admin/collections/book_page`, which leads to an error. Accessing `http://fusionv6.test/admin/collections/book-page` loads the matrix as expected.
