Staking contract query - block_height from past

[pronvis]

Hello guys!
Found issue in my Staking contract (that was copypasted from yours): Nexus-Protocol/services-contracts#17

Your code here:

anchor-token-contracts/contracts/staking/src/contract.rs

Line 289 in cac5a72

fn compute_reward(config: &Config, state: &mut State, block_height: u64) {

have the same issue

If you pass block_height from the past this part:

let passed_blocks = std::cmp::min(s.1, block_height) - std::cmp::max(s.0, state.last_distributed);

will fail

@pronvis Thanks for the report, yes that causes a problem in the query. We will reflect this in our new update.
