Remove config lines that cause failure

[matthewrmshin]

Following JCSDA-internal/ufo#3438, we have failures that look like:

74/152 Test  #75: test_opsinputs_varobswriter_ukvnamelist_surfacecloud ......................***Failed

...

Test "ufo/ObsFilters/testFilters" failed with unhandled exception: Column 'field':
  received: [15,15,15,15,15,15,15,15,15]
  expected: [15,15,15,15,15,15,15,15,15,15,15,15]
Completed case 0: ufo/ObsFilters/testFilters
  FAILED: ufo/ObsFilters/testFilters
1 tests failed out of 1.
Finished running the unit tests, result = 1
SurfaceCloud :  no output

This change fixes the failure.

Suite output with this fix. http://fcm1/cylc-review/taskjobs/frsn/?suite=mobbm-fixopsinputs

• The suite is still running as I am write this, but the ctest_all_opsinputs__* tasks have all succeeded.

I'll merge to prevent daily build issues.
