[Bug] Using simple float values inside sympy function leads to incorrect wavefunction when using time-dependent block

[vytautas-a]

Say we define a time-dependent generator for HamEvo:

td_gen = omega * (sympy.sin(x * t) * X(0) + y * (t**2) * Y(1))

If x and y are instances of Parameter (t is the time parameter) the result of simulating HamEvo with such generator is correct. However, if either or both x and y are floats or tensors - the simulation result is wrong.

@vytautas-a Would you be able to give it a try ?

To check again in PyQ once pasqal-io/pyqtorch#228 is done.
