Fix conduit disconnections

[Metalit]

Description

Changes disconnections of blocks from the conduit network to remain a DynamicConnectionState, from wrench or gui interactions. This fixes an issue with the GUI opening an invalid connection and not being able to change any settings. It also simply improves the usability of disconnected conduits, as without this change, it would be fairly annoying to reconnect them, especially with a multi-conduit bundle.

I decided to not drop any filters when the connection is disabled, and instead only when the conduit or block it's connected to is broken. That could be changed though.

To reproduce the GUI issue without these changes, place an item and fluid conduit next to a fluid tank and disconnect the item conduit, then click on the item conduit in the bundle.

I'm aware that this bug could be fixed in other ways, but I chose this one because of the usability reasons.
