Title: Call #to_s when serializing GlobalID. Fix #95

This is another approach to fix #95 by calling `to_s` when serializing ActiveModel::GlobalId object, so that there's no ambiguity about how to serialize GlobalId object regardless of the queue backend.

Thanks to @zzak for the suggestion :heart:
