disable kelp update test

[knewmanTE]

As mentioned in #2235, some frameworks are (I assume unintentionally) modifying the structure of the MongoDB World documents by removing the id field, leaving only the _id and randomNumber fields. For example, the collection goes from this:

{ "_id" : 1, "id" : 1, "randomNumber" : 7229 }
{ "_id" : 2, "id" : 2, "randomNumber" : 5321 }
{ "_id" : 3, "id" : 3, "randomNumber" : 9144 }
{ "_id" : 4, "id" : 4, "randomNumber" : 9358 }
{ "_id" : 5, "id" : 5, "randomNumber" : 4414 }
{ "_id" : 6, "id" : 6, "randomNumber" : 5760 }
{ "_id" : 7, "id" : 7, "randomNumber" : 6196 }
{ "_id" : 8, "id" : 8, "randomNumber" : 5389 }
{ "_id" : 9, "id" : 9, "randomNumber" : 5945 }
{ "_id" : 10, "id" : 10, "randomNumber" : 6208 }

to this:

{ "_id" : 1, "id" : 1, "randomNumber" : 7776 }
{ "_id" : 2, "id" : 2, "randomNumber" : 7637 }
{ "_id" : 3, "randomNumber" : 3636 }
{ "_id" : 4, "randomNumber" : 4423 }
{ "_id" : 5, "id" : 5, "randomNumber" : 9595 }
{ "_id" : 6, "randomNumber" : 5993 }
{ "_id" : 7, "id" : 7, "randomNumber" : 3051 }
{ "_id" : 8, "id" : 8, "randomNumber" : 5884 }
{ "_id" : 9, "randomNumber" : 3341 }
{ "_id" : 10, "randomNumber" : 8440 }

Out of fairness to the other frameworks that need to access the same MongoDB collections, this PR disables the update test for Perl/kelp until the issue has been resolved.
