Fix hot reload

[DylanPiercey]

Description

Currently marko.load can cause issues with hot reloading, especially when precompiled files from Marko CLI are discovered (or if there is a naming conflict between a marko file and a js file).

This PR ensures that if you are using the require hook that any subsequently loaded template also uses the require hook and makes the hot-reload functionality also use the require hook if available.

Fixes #1282.
