Pause in _retry_read_url should only happens from the second time

Hi,

I noticed in utils.py in _retry_read_url this

def _retry_read_url(url, retry_count, pause, name):
    """
    Open url (and retry)
    """
    for _ in range(retry_count):
        time.sleep(pause)
        ...

So an unnecessary pause occured from begining (first request)

we might have something like:

def _retry_read_url(url, retry_count, pause, name):
    """
    Open url (and retry)
    """
    for i in range(retry_count):
        if i != 0:
            time.sleep(pause)
        ...
