Fixes a bug regarding commit 2a6ddca3adb80fc1b026ae116e584b2b5fa7a9f1.
Now, dalvik constants get initializers in clinit. However, soot could
generate code like

public void <clinit>() {
  <a.a: int a> = 2;
  return;
  <a.a: int b> = 2;  //This line is created by
ConstantValueToInitializerTransformer
  return;  //This line is created by
ConstantValueToInitializerTransformer
}

After this fix:

public void <clinit>() {
  <a.a: int b> = 2;  //This line is created by
ConstantValueToInitializerTransformer
  <a.a: int a> = 2;
  return;
}
