Subject: [PATCH] General: Throw a more descriptive error when templates are
 not found.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When `wp.template()` is called in JavaScript for a template element that does not exist, a very nondescript error message is currently returned (“Uncaught TypeError: Cannot read property `replace` of `undefined`”).

This updates adds a check for this scenario and a new “Template not found” error is now thrown instead.

Props joehoyle, noisysocks, hilayt24.
Fixes #36631.
