Fix frozen Yr weather-module

[MagMar94]

Fixes #3296

The problem was that the fetch-methods threw errors when something went wrong instead of calling updateAvailable(). updateAvailable() must be called in order to schedule the next update.

I added some filtering for the hourly forecast that removes hours in the past. If the API call fails we use the cached data, but we should only display hours in the future.

I tried setting the updateInterval in the start-method with this.config.updateInterval = 600000 and this.setConfig({ ...config, updateInterval: 600000 }), but the setInterval still used the original value.

can confirm this, so we live with the error message instead. Or may @rejas has an idea how to change config.updateInterval within a provider?

after some digging in the code I found in weatherprovider.js this part

WeatherProvider.initialize = function (providerIdentifier, delegate) {
	const pi = providerIdentifier.toLowerCase();

	const provider = new WeatherProvider.providers[pi]();
	const config = Object.assign({}, provider.defaults, delegate.config);

	provider.delegate = delegate;
	provider.setConfig(config);
...

which explains the behavior.

So I tested this.delegate.config.updateInterval = 123456; inside the provider (in setConfig) which works. So if you are willing to change it again for better user experience ...
