Allow specifying "break chain on failure" flag as option

- When calling `attachByName()`, allow passing the "break chain on failure" flag
  as an option, instead of requiring it to be passed as the third argument to
  the method; simplifies factories.

- Fixes zfcampus/zf-apigility-admin#89
Ensure both flags are tested

- Wrote a data provider so that the option name both with and without
  underscores may be tested.
