MPS-19144 Solution jetbrains.mps.ide.make fails to generate when in-place transformation is enabled.
ReferenceMacro relies in inputModel.nodes<concept> query to find input node to match output by label. Replaced with MAP_SRC and direct template reference - same model element. In fact, MAP_SRC is redundant (plain template reference works fine), and is there only to utilize the same source nodes query. Indeed, plain template reference would fail if there'd be more than one output for the given template node, however, generation would fail earlier as it's incapable to deal with cases when there are more than one StandalonePluginDescriptor in the model anyway (class name doesn't depend on instance). And, by the way, it's stupid way to flag model  (SPD does nothing but serves as boolean flag, present-not).
