If number of hyperparameter combinations are small the Hyperband tuner stops at the first round.

The problem is at

https://github.com/keras-team/keras-tuner/blob/215603d4a728a6e3cab47fb26da0e5322af565bf/keras_tuner/tuners/hyperband.py#L144

if no parameter choice is available, i.e. number of choices are less than self._get_size(), None is returned and the tuner stops with doing the successive halving.
