The PR will corerce routes that have a leading slash and throwing a _doing_it_wrong notice while ensuring a proper namespace.

This brings the changes from <a href="https://core.trac.wordpress.org/changeset/47842">[47842]</a> to the 5.4 branch.

Fixes <a href="https://core.trac.wordpress.org/ticket/49749">#49749</a>.
