Expected exception when incorrectly configuring upsert has changed (#1878)

AbstractMROldApiSaveTest.testUpdateWithoutId broke when #1839 was merged because we are now failing earlier if
upsert is used but es.mapping.id is not set. The exception is now the same as the one you get when update is not
configured to use es.mapping.id.
Relates #1839 #69
