Duplicated Operations in Mutate Requests

[BenRKarl]

In the Ads templates, here, the below logic is generated for our operations parameter, an example from proto can be found here: MuateAdGroups and MutateAdGroupsRequest

if customer_id is not None:
    request.customer_id = customer_id
if operations is not None:
    request.operations = operations

if operations:
    request.operations.extend(operations)

If operations is present, request.operations is set, and request.operations.extend is also called, causing our operations to be duplicated in any request.

Good catch.
