ProgramSet num_executables incorrectly assigned with non-indexed TensorProduct

[sesmart]

Describe the bug

Running a variant of #1166, with input parameters specified, leads to a modulo division error in running a ProgramSet. Apparently num_executables is registered as 0 without non-zero programs.

To reproduce

device.run(ProgramSet(
    CircuitBinding(
        circuit=Circuit().h(0).h(1),
        observables= [Z() @ Z()],
        input_sets=[{"alp":0}]
    ), shots_per_executable=100)).result()

Expected behavior

Should run okay?

Screenshots or logs

--> 690 shots_per_executable, remainder = divmod(shots, program_set.num_executables)
691 if remainder:
692 raise ValueError("Total shots must be divisible by number of executables.")

ZeroDivisionError: integer division or modulo by zero
