Andrew McCreight bfd580fb71 Bug 1186409 - Use Cu.getGlobalForObject when importing properties off a JSM global. r=kmag
With JSM global sharing, the object returned by Cu.import() is a
NonSyntacticVariablesObject, rather than a global. Various code tries
to use properties from a JSM global via an import.

Cu.importGlobalProperties can also be used in some places.
