#1202: fix some CarpetProlongationTest tests

 Reporter:  rhaas   |       Owner:  eschnett
     Type:  defect  |      Status:  new     
 Priority:  minor   |   Milestone:          
Component:  Carpet  |     Version:          
 Keywords:          |  
--------------------+-------------------------------------------------------
 the attached patch fixes (by adjusting the domain which was created before
 CarpetRegrid2 changed its property enforcement logic) some tests in
 CarpetProlongationTest and also restricts those tests that produce Carpet
 1D ouptut to 1 or 2 processes (depending on how many were apparently used
 to create the test).

 For some tests (test_o1 test_cc_rest_o0 test_cc_rest_o1) I could not make
 the code agree with these measures and since they also show differences in
 a "sum" reduced quantity I replaced the "sum" data by errornorm 0D output
 (and had to regenerate the data because of this). I am not sure what the
 expected smallness of errornorm is.
