AWS Braket SearchQuantumTasks not recognized by the heuristic

[JohannesEbke]

The Braket SearchQuantumTasks and SearchDevices APIs are such that they require a list as "filters" argument, yet this list can be zero-length. Therefore, there is no equivalent "ListQuantumTask" as in other services.

Relevant API documentation:
https://docs.aws.amazon.com/braket/latest/APIReference/API_SearchQuantumTasks.html
https://docs.aws.amazon.com/braket/latest/APIReference/API_SearchDevices.html

Example code illustrating the problem even without any Quantum Tasks:

boto3.client("braket", region_name="us-east-1").search_devices(filters=[])
