Remove assumption of tab/window order back from browsers

[christian-bromann]

The code inclose.js assumes order is the order of creation and [0] is the "original" tab, this is not true and can cause race conditions when closing a new tab that is presented at [0] in the "windowsHandles()" return.

Environment (please complete the following information):

• WebdriverIO version: 4.14.3
• Mode: N/A
• If WDIO Testrunner, running sync/async: N/A
• Node.js version: N/A
• NPM version: N/A
• Browser name and version: IE 11
• Platform name and version: macOS (Mojave)
• Additional wdio packages used (if applicable): Lots

Config of WebdriverIO
N/A

Describe the bug
IE doesn't return tabs/windows in the order created this will cause issues with places that assume order (i.e. close.js)

To Reproduce
Not exactly easy as we need to wait for IE to give back the tabs in different orders

Expected behavior
A clear and concise description of what you expected to happen.
