`nk.dynamics.TDVP.run(T, tstops=...)` progress bar does not get updated if T > tstops[-1]

Created by: PhilipVinc

The progress bar is printed at every tstop. But if there are no tstops it is never printed, which is annoying, even if not super-important.

Noticed by running te.run(T=1.0, tstops=np.linspace(0.0, 0.5, 51, endpoint=True)) in the example
