Consider SocketException as network error

[poovamraj]

Changes

Currently NetworkErrorException is not working properly. The following comment is added for it to be fixed in the next major

// When the request failed due to network issues
// Currently [NetworkErrorException] is not properly thrown from [createErrorAdapter] in
// [AuthenticationAPIClient] and [UserAPIClient]. This will be fixed in the next major to avoid
// breaking change in the current major. We are not using IOException to check for the error
// since it is too broad.

As it can be seen in the previous PR - #235. NetworkErrorException should be thrown if OkHttp fails because of network issues. But currently this is not being done

A valid issue was raised to conside SocketException as a network error - #657. We are fixing this by adding it to the assertion
