fix(esp_http_client): Fix invalid content length header

Browse Source 
In case a request with no content is sent after one with the content
length header set the header of the previous request is sent with the
subsequent one.
For instance, an empty GET request after a PUT request will still
indicate the non-zero content length of the previous request.

This is fixed by clearing the content length header when it shouldn't be
set.
