The method currently catches errors that occur when calling the extension's init() method, but throws itself an error if the expected extension.js file is missing. The former is pointless if we expect all callers to handle errors themselves anyway, and we should avoid the latter if we don't - opt for the second option and handle a missing extension.js file gracefully. https://bugzilla.gnome.org/show_bug.cgi?id=781728
