Revert of permissions: add layout tests for multiple requests

Revert of permissions: add layout tests for multiple requests (patchset #8 id:140001 of https://codereview.chromium.org/1352863003/ )

Reason for revert:
Oddly one test is failing on Win7: 535931. Sorry for the revert.

Original issue's description:
> permissions: add layout tests for multiple requests
>
> No permisisons, single, multiple and duplicate permissions
> are all tested. Permission updates being reflected in the request
> is also tested.
>
> This CL depends on https://codereview.chromium.org/1352863002/
> as it adds the ability to reset permisisons.
