use --project tsconfig.json to suppress lint error

[jacobbubu]

When I run npm run lint, i get the following warnings:

Warning: The 'await-promise' rule requires type information.
Warning: The 'no-unused-variable' rule requires type information.
Warning: The 'no-use-before-declare' rule requires type information.
Warning: The 'return-undefined' rule requires type information.
Warning: The 'no-floating-promises' rule requires type information.
Warning: The 'no-unnecessary-qualifier' rule requires type information.
Warning: The 'no-unnecessary-type-assertion' rule requires type information.
Warning: The 'strict-type-predicates' rule requires type information.

Add --project tsconfig.json option to 'tslint' can eliminate these warnings.

"scripts": {
  "lint": "tslint -t codeFrame --project tsconfig.json 'src/**/*.ts' 'test/**/*.ts'",
  ...
}
