Nested internal call - merged parameters

| Q | A
| ----------------- | ---
| Bug? | yes
| New Feature? | no
| Framework | Laravel
| Framework version | 5.2.45
| Package version | v1.0.0-beta8
| PHP version | 7.1.18

#### Actual Behaviour

In place A I'm making internal request with some data to place B. In place B there is another internal request with different data to place C. As Dingo\Api\Dispatcher is a singleton, the parameters from first request remains in instance, they are merged with data from place B and send along to place C, but in place C I only need data from B. I can't see any way to reset internal dispatcher parameters.

#### Expected Behaviour

Place C get only parameters from place B.

#### Steps to Reproduce

1. Make internal call with some data to endpoint which has another internal call (nested internal call).
2. Final controller method is getting merged data from both requests.

#### Possible Solutions

Allow manually reseting parameters?
