Removing non-existent intermediate sub-key should not throw an exception

The current behavior for removing a sub-key is this:

Object subObject = getFieldValueListSafe(document, mainKey);
if (subObject instanceof Document || subObject instanceof List<?>) {
   return removeSubdocumentValue(subObject, subKey, matchPos);
} else {
   throw new MongoServerException("failed to remove subdocument");
}

With the code above, if an intermediate sub-key is missing, an exception will be thrown. It is perfectly reasonable that an intermediate sub-key does not exist on the document in question. If it doesn’t, the operation (remove or rename) should be ignored for that document.

Yep 😃 Found one more weird case that I’m trying to iron out…

Yep, working on it as we speak.
