ProcNetTest.java - reverse arguments to assertEquals()

currently we have:
  org.junit.ComparisonFailure: expected:<[]bic> but was:<[cu]bic>
	at org.junit.Assert.assertEquals(Assert.java:117)
but this is the reverse of the intended error:
  org.junit.ComparisonFailure: expected:<[cu]bic> but was:<bic>
	at org.junit.Assert.assertEquals(Assert.java:117)

method signature:
  public static void assertEquals(Object expected, Object actual)

Test: N/A
