Duplicate vote triggered cross-repo

[7db9a]

After voting on a pull request in "repo A" with the same repo name, github issue/pull number, commit oid, and default hash as "repo B", I was unable to vote on the "duplicate" pull requests on "repo B".

This duplicateVote triggered when looking at turbosrc-engine logs:

    const duplicateVote = await Vote.findOne({
      where: { defaultHash: defaultHash, contributor_id: contributor_id },
    });

    if (duplicateVote) {
      console.log("duplicate");
      return 403;
    } else {
      let tokens = await getVotePowerAmount(
        /*owner:*/ "",
        /*repo:*/ repo_id,
        /*defaultHash:*/ defaultHash,
        /*contributor_id:*/ contributor_id,
        /*side:*/ ""
      );

      // Should also check if tokens.status === 404
      if (tokens.amount < 1) {
        return 403;
      }

      let vote = await Vote.create({
        contributor_id: contributor_id,
        defaultHash: defaultHash,
        votePower: tokens.amount,
        side: side,
      });

      await vote.setPullrequest(pullRequest.id);

      if (side === "yes") {
        let newTotal = pullRequest.yesTokenAmount + tokens.amount;
        await pullRequest.update({
          yesTokenAmount: newTotal,
          where: { id: pullRequest.id },
        });
      }
      if (side === "no") {
        let newTotal = pullRequest.noTokenAmount + tokens.amount;
        await pullRequest.update({
          noTokenAmount: newTotal,
          where: { id: pullRequest.id },
        });
      }

      return 201;
    }
  } catch (error) {
    console.log(error);
    return 500;
  }```
