ContentRestore.jsm is only needed when we're actually restoring the contents of a tab, which doesn't happen that often. The gContentRestore instance is created lazily, but the JSM is always imported eagerly.

Looks good, thanks! I'm particularly pleased that we have a test that'll catch if this somehow regresses.
