Fix pyload API statusServer doesn't take parameters

[h4de5]

Proposed change

Pyload's API method "statusServer" never accepted parameters. A recent update to payload's integrated webserver (which fixed the SSL connection handling) enforced this rule. Therefor the sensor no longer worked.

Remove json payload from API call to statusServer for retrieving current download speed.
Skip duplicated call to update function.

Thanks! This is ok since it only removes code. We won't allow any additions to this integration though since the service specific interface code and data parsing should be moved to a standalone library published on pypi.
