Minor breaking changes

This release includes a few minor breaking changes:

1. Error message format has changed (we do not recommend having code depend on error messages though).
2. When a standard Go error is converted to ApplicationFailure and then to ApplicationError, the failure type used to be set as errorString. Now it is just an empty string as no actual failure type was defined.
3. Tracer propagator header name has changed. It means that Workflows started with an older SDK version will loose trace information if the Workflow continues with this version.
