Invalid time series mapping values just disappear

[sebastian-peter]

If there's an error during mapping entry creation, the failure is just filtered out. It should be thrown instead.

Lines 43 to 50 in 6b3b06b

	public Map<UUID, UUID> getMapping() throws SourceException {
	return getMappingSourceData()
	.map(this::createMappingEntry)
	.filter(Try::isSuccess)
	.map(t -> (Success<MappingEntry, FactoryException>) t)
	.map(Success::get)
	.collect(Collectors.toMap(MappingEntry::getAsset, MappingEntry::getTimeSeries));
	}
