`customerId` and `cartId` params not being reset between calls to `build`

### Description

When using `byCustomerId` or `byCartId` in `api-request-builder`, the locally stored params are not cleared before the next call to `build`.

### Expected Behavior

The `setDefaultParams` function should reset the `customerId` and `cartId` params.

### Current Behavior

The `customerId` and `cartId` params are not cleared between calls to `build`.

### Context

This bug was discovered when attempting to build multiple queries, one after the other.

### Possible Solution

Will create a PR shortly.
