v2.7.26

#Changed behaviour of _reques() method.

The instaclient._request method loads the request output from Instagram

Sometimes, Instagram asks to log in before allowing incoming requests.

In the previous version, the _request method would wait 5 seconds before trying again.

This change reduces the wait time to 2 seconds and removes any retries to find the WebElement containing the GraphQL response - instead, a instaclient.errors.common.NotLoggedInError will be raised
