Suppress error between 00:00 and 01:00 (home-assistant#15555)

* Suppress error between 00:00 and 01:00

Suppress an error that often occers between 00:00 and 01:00 CE(S)T during that time, probably because buienradar.nl is then updating its forcast for the next day. The API does not always work between these times (in the middle of the night).

* white space & import

* unnecessary brackets
