Fixes local-to-remote joined transformer apply

as the next in the sequence would fail because the compatibility of the
receiving resource would be rechecked, but the remote transformer's
accepts schema had not been retrieved. This small change corrects that.
Fixes JSON syntax error in relation definitions

A semi-colon had been used in place of a comma in some relation
definition files. Although Gson was able to parse them successfully, the
error has now been corrected.
