feat(SELENIUM_PROMISE_MANAGER): Support
SELENIUM_PROMISE_MANAGER=0
There are three major ways this was done in this change: * In `callWhenIdle`, if `flow.isIdle` is not defined, we assume we are working with a `SimpleScheduler` instance, and so the flow is effectively idle. * In `initJasmineWd`, if `flow.reset` is not defined, we assume we are working with a `SimpleScheduler` instance, and so don't bother resetting the flow. * In `wrapInControlFlow`, we use `flow.promise` to create a new promise if possible. Since `new webdriver.promise.Promise()` would have always made a `ManagedPromise`, but `flow.promise` will do the right thing. * In `wrapCompare`, we avoid the webdriver library entirely, and never instance any extra promises. Using `webdriver.promise.when` and `webdriver.promise.all` could have been a problem if our instance of `webdriver` had the control flow turned on, but another instance somewhere did not (or even the same instance, but just at a different point in time). Instead we use the new `maybePromise` tool, which is a mess but is also exactly what we want. * In `specs/*`, we replace `webdriver.promise.fulfilled` with `webdriver.promise.when`. * In `specs/*`, a new version of `adapterSpec.js` and `errorSpec.js` are created: `asyncAwaitAdapterSpec.ts` and `asyncAwaitErrorSpec.ts`. I also also fixed a minor bug where we weren't correctly checking for promises inside an array of expected results. Before we had ```js expected = Array.prototype.slice.call(arguments, 0) ... webdriver.promise.isPromise(expected) ``` I thought about it for a little while, and there's no way that's correct. `expected` is an `Array<any>`, there's no way it has a `.then` function. Closes #69
