aws s3api list-object-versions: specifying --starting-token errors with "Cannot specify --no-paginate along with pagination arguments: --starting-token", even though --no-paginate is not set.

```
❯ aws --version
aws-cli/1.11.76 Python/2.7.10 Darwin/16.5.0 botocore/1.5.3
```

`aws s3api list-object-versions`:

specifying --starting-token errors with :

```
Cannot specify --no-paginate along with pagination arguments: --starting-token
```

even though `--no-paginate` is **not set**.

Working:
```
aws s3api list-object-versions --bucket my-bucket --key my-prefix/
# works
```

Error:
```
aws s3api list-object-versions --bucket my-bucket --key my-prefix/ --starting-token foo/bar

Error during pagination: Cannot specify --no-paginate along with pagination arguments: --starting-token
```

I'm not specifying `--no-paginate`, yet still seeing the error. Possibly related to #2554
