ut optional within UtExpressionCompositeMatcher not working as expected

[JustinChilton]

I would expect the ut optional token to work even if there are not the same number of arguments (because that arg would be optional). Below is an example that I would expect to pass.

Names Default To Here( 0 );
ut global reporter = ut streaming log reporter();
dt = Open( "$SAMPLE_DATA\Big Class.jmp" );
gb = dt << Run Script( "Graph Builder Smoother Line" );
ut assert that(
	Expr( gb << get script ),
	ut expression matches(
		Expr(
			Graph Builder(
				ut optional( size( ut wild(), ut wild() ) ),
				Show Control Panel( 0 ),
				Variables( X( :height ), Y( :weight ), Overlay( :sex ) ),
				Elements( Points( X, Y, Legend( 1 ) ), Smoother( X, Y, Legend( 2 ) ) )
			)
		)
	)
);

I wrote this matcher a long time ago, so I am not sure what the behavior was meant to be, but I think it is supposed to support this.
