[bug] miner reward given could be lower than the entry fee

[0xzoz]

Describe the bug @Nima2(Discord) found a potential issue in the codebase.

We might not be awarding miners with any rewards atm, because of this little issue. In the case that the thermostat lowers the reward, and the entry fees are already super high, we might hit the scenario where the reward given will be lower than the entry fee. Now, that should not really happen logically, but it does happen sometimes, as it did in some previous epochs (this was the cause of the last halt)..

To Reproduce The lowest bid from a validator is above the reward value at the end of an epoch.

Expected behavior

Screenshots get_consensus_reward returns these values reward, entry_fee, clearing_bid, median_win_bid respectively.

@nonast I believe this was resolved?
