genMaciStateFromContract does not fetch any events if fromBlock and endBlock is the same

Prerequisites

Please answer the following questions for yourself before submitting an issue.

• I am not running a deprecated version
• I checked the documentation and found no answer
• I checked to make sure that this issue has not already been filed

Expected Behavior

The function should process events even though the fromBlock and endBlock is the same. This is a minor issue as this situation only occurs in test environment when all events occurred in 1 block.

Current Behavior

As seen in this line https://github.com/privacy-scaling-explorations/maci/blob/dev/contracts/ts/genMaciState.ts#L62, the code does not enter the for loop if fromBlock === lastBlock

for (let i = fromBlock; i < lastBlock; i += blocksPerRequest + 1) {
