fix add-cognito-user-pool-trigger extra parameters

[gardun0]

Hey! as the spec from updateUserPool changed, claudia wasnt able to update the user pool, so in order to do that, I modified the cleanUpPoolConfig to remove extra parameters.

Already tested locally and tests completed

This was the output before:

MultipleValidationErrors: There were 2 validation errors:
* UnexpectedParameter: Unexpected key 'CustomDomain' found in params
* UnexpectedParameter: Unexpected key 'UsernameConfiguration' found in params
