Joshua Spence f15b74b4a4 Fix DB parameter group name property ...

It appears that #13232 doesn't work properly if you actually try to set any `parameter`s. Specifically, I was getting the following error:

```
* aws_db_parameter_group.test: 1 error(s) occurred:

* aws_db_parameter_group.test: Error modifying DB Parameter Group: InvalidParameterValue: The parameter DBParameterGroupName must be provided and must not be blank.
	status code: 400, request id: 5783e396-17ff-11e7-87d5-e3fd4c7025ce
