Pull Request check-list

Please make sure to review and check all of these items:

• Does npm run test or npm run test-DIALECT pass with this change (including linting)? (see below)
• Does the description below contain a link to an existing issue (Closes #[issue]) or a description of the issue you are solving?
• Have you added new tests to prevent regressions? (not new but changed the existing ones)

• Did you follow the commit message conventions explained in CONTRIBUTING.md? (this is my first PR but hopefully yes)

npm run test-mssql fails but it failed for me before my changes. After my changes it only fails at the same place:

> sequelize@5.0.0-beta.3 test-integration /tmp/sequelize
> mocha $npm_package_options_mocha "test/integration/**/*.test.js"

FIXME: I want to be supported in this dialect as well :-(
