Some descriptions don't match test cases

[dmolesUC]

In validComparisonString.json, the test cases are all things like:

{
  "description": "subfield with single lowercase alpha subfieldtag",
  "data": "test\\$",
  "valid": true
}

The description subfield with single lowercase alpha subfieldtag doesn’t seem to have anything to do with comparison strings or with this particular test. The other test case descriptions similarly all talk about subfields, except for the last one.

Similarly, in validSubSpec.json the test descriptions seem to be taken from validFieldTag:

{
  "description": "two wildcards left with digit",
  "data": "{$a}",
  "valid": true
}
