In certain cases (e.g. on LG webOS using the `file:` protocol), access to `document.cookie` may not be allowed and throw an error. This could break `$http` which relies on `$$cookieReader()` for retrieving the XSRF token. This commit fixes it by treating `document.cookie` as empty, when access to it is fordibben. Fixes #15523 Closes #15532
