ISW: Routing to streams via pipeline rules leads to pipelines connected to Default Stream being executed

## Expected Behavior

When I create an input with the new input setup wizard and let it create a stream & enable "Remove matches from ‘Default Stream’" (all nicely separated), no other pipelines besides the one that is created will be run for messages ingested into that input.

## Current Behavior

When pipelines are pre-existing that are connected to the "Default Stream", those will be executed for all messages coming in to another input which has its own stream & index set, has "Remove matches from ‘Default Stream’" configured, but is routed through pipelines.

## Possible Solution

Set up stream routing through ISW with generic stream rules instead of pipelines?
