When the replacement name for mp-syndicate-to (and mp-slug) are the default, these params aren't send

If syndicateName equals "mp-syndicate-to" the delete on the next line will remove the only copy. And then it isn't send. Parameter "mp-slug" has the same problem.

When the syndicateName is replaced with something else, for example, the non default "slug" value, then the value will be send to the micropub endpoint.
