Anton Kaliaev	50b87c3445	state: Use last height changed if validator set is empty (#3560 ) What happened: New code was supposed to fall back to last height changed when/if it failed to find validators at checkpoint height (to make release non-breaking). But because we did not check if validator set is empty, the fall back logic was never executed => resulting in LoadValidators returning an empty validator set for cases where `lastStoredHeight` is checkpoint height (i.e. almost all heights if the application does not change validator set often).

state: Use last height changed if validator set is empty (#3560 )

What happened:

New code was supposed to fall back to last height changed when/if it
failed to find validators at checkpoint height (to make release
non-breaking).

But because we did not check if validator set is empty, the fall back
logic was never executed => resulting in LoadValidators returning an
empty validator set for cases where `lastStoredHeight` is checkpoint
height (i.e. almost all heights if the application does not change
validator set often).

How it was found:
