Remove unused originalIndex from acceptParams

Remove unused originalIndex from acceptParams in express/lib/utils.js

[dougwilson]

Hello, and thank you for your pull request. Unfortunately even though Express.js itself may not use this param, external code commonly uses the functils in our utils, so the API for them is frozen due to external usage. I hope that makes sense.

Apologies, acceptParams is not an exported function I think.

Thanks @dougwilson!

From my analysis, the only way to observe originalIndex from outside of Express is if you are doing a deep require into the utils file, and are calling normalizeType directly. Even so, originalIndex is always undefined, so it's only observable if doing 'originalIndex' in result.

Since we don't support deep requires into internals, and since even if someone did this it's very unlikely to affect anyone, I think that we can merge this 👍

const utils = require('express/lib/utils')

'originalIndex' in utils.normalizeType('foo/bar')

The code above previously evaluated to true, but will become false with this patch.

Annoyingly we do in 4.x, but it doesn't matter, as like you observed, the functionality doesn't actually "produce" anything -- a property that is defined on the object in a technical sense, but extremely unlikely to actually break anything with it's removal 👍

Whoops, my bad. Good to know 👍
