Numpy 2: "The truth value of an empty array is ambiguous." is an an error

[jvesely]

The original DeprecationWarning:

tests/functions/test_memory.py::TestContentAddressableMemory::test_ContentAddressableMemory_simple_distances
  /Users/runner/work/PsyNeuLink/PsyNeuLink/psyneulink/core/components/functions/stateful/memoryfunctions.py:396: DeprecationWarning: The truth value of an empty array is ambiguous. Returning False, but in future this will result in an error. Use `array.size > 0` to check that an array is not empty.
    test_val = np.array([int(np.array(val).item()) if val else 0 for val in value])

turns into an error with Numpy 2:

>       test_val = np.array([int(np.array(val).item()) if val else 0 for val in value])
E       ValueError: The truth value of an empty array is ambiguous. Use `array.size > 0` to check that an array is not empty.
