    Correctly filter events on resource name

    Filtering on resource name can be accomplished by using the db
    filters instead of using a filter method. Furthermore, using a
    custom filter breaks certain assumptions made by other parts of
    the codebase, which lead to pagination being broken.
    Specifically, custom filter for resource name is applied only
    after other filtering is finished. As a result, we try to find
    result from only 1 event and this event belongs to whole
    stack and thus its resource_name is equal to the stack name.
    This returns an event not found error instead of returning
    the first event assosciated with the resource name.
