Title: FIX: Fixes filter related fuctions (in business rules processing)

When configuration is incorrect (unknown or wrong host/service parameter), exceptions may be risen by business rules parsing in `filter*` callbacks related functions (passed host/service may be None) before error massage can be displayed.

This fixes this issue by checking that all required parameters are set.
