Fixes two Roo issues: ROO-1238 (Amit) and ROO-1380 (pdr)

ROO-1238:
* Remove SyncResults.
* Use EntityProxyId and  RequestFactory.find(EntityProxyId) instead of the id
field of EntityProxy (or a ProxyImpl with just the id and schema fields).

ROO-1380:
* Removes RequestFactory::getProxy(String), replacing it with
getProxyId(String).
* Removes the EntityProxy.asString() method, and fixes one
incorrect usage of it.
* Adds getToken(EntityProxyId).
* Renames getToken() to getHistoryToken() in RequestFactory.
