fix a typo in comments of test/protocol/modules/aaveLeverageModule.spec.ts

[gzliudan]

change Issue 10 SetToken to Issue 1 SetToken:

      // Issue 10 SetToken. Note: 1inch mock is hardcoded to trade 1000 DAI regardless of Set supply
      const issueQuantity = ether(1);
      await setup.issuanceModule.issue(setToken.address, issueQuantity, owner.address);
