Issue Description:

Without providing a value for `HTTPCookiePropertyKey.path`, it is not possible to create an `HTTPCookie`, even though the documentation states that this field is optional.

Relevant part of the documentation (in `Foundation -> NSHTTPCookie -> HTTPCookie`)

        <tr>
            <td>NSHTTPCookiePath</td>
            <td>NSString</td>
            <td>NO</td>
            <td>Path for the cookie. Inferred from the value for
            NSHTTPCookieOriginURL if not provided. Default is "/".</td>
        </tr>

However, the following code did not create an HTTPCookie for me (it returned `nil`):

HTTPCookie(properties: [HTTPCookiePropertyKey.name: "name", HTTPCookiePropertyKey.value: "value", HTTPCookiePropertyKey.domain: "localhost"])

The following code worked:

HTTPCookie(properties: [HTTPCookiePropertyKey.name: "name", HTTPCookiePropertyKey.value: "value", HTTPCookiePropertyKey.domain: "localhost", HTTPCookiePropertyKey.path: "/"])
