Serial filter(...) expression: Missing filter operations in generated code

[maxkratz]

(This issue may be related to #90, but maybe it is a duplicate and I did not get the issue right the first time.)

At least in some cases, concatenated filter(...) expressions do not produce correct generated code:

objective formerValue -> mapping::move {
	patterns.findComponentInFormerSystem
		->filter(m | m.nodes().s == self.nodes().newSystem)
		->filter(m | m.nodes().c1 == self.nodes().component)
		->count()
		* self.value()
}

Generated code:

@Override
protected void buildTerms(final MoveMapping context) {
terms.add(new ILPTerm(context, engine.getEMoflonAPI().findComponentInFormerSystem().findMatches(false).parallelStream()
			.filter(itr_0 -> itr_0.getS().equals(context.getNewSystem()))
			.map(itr_0 -> 1.0 * 1.0)
			[...]
}
