Enforce consistent param names when creating new promises (param-names)

Enforce standard parameter names for Promise constructors

🔧 The --fix option on the command line can automatically fix some of the problems reported by this rule.

Valid

new Promise(function (resolve) { ... })
new Promise(function (resolve, reject) { ... })

Invalid

new Promise(function (reject, resolve) { ... }) // incorrect order
new Promise(function (ok, fail) { ... }) // non-standard parameter names

Ensures that new Promise() is instantiated with the parameter names resolve, reject to avoid confusion with order such as reject, resolve. The Promise constructor uses the RevealingConstructor pattern. Using the same parameter names as the language specification makes code more uniform and easier to understand.
