Should be completely transparent. It'll fail the unit tests though because it now pretends that all printers have machine nodes.
Contributes to issue CURA-6793.
When switching printers, it would first emit the global container changed signal which connects to _onGlobalContainerChanged, then update stuff in the extruder manager, then manually call _onGlobalContainerChanged again to update some other stuff with the new data from the extruder manager. This was prohibitively expensive, so this prevents that.
Another double or triple emit of the activeExtruderChanged was removed in the extruder manager when creating the extruders for a printer: It would first set the extruder number to 0, possibly emitting the signal, then emit the signal just to be sure since the extruder itself changed (rather than just the number), and then change the extruder number to the preferred extruder, possibly again emitting a signal. Now it just sets the extruder number to the preferred extruder and always emits the signal once (either through setting the extruder number or manually afterwards).

The extruders are added when changing printers anyway, and we call this change signal upon start-up. So one of them is going to do unnecessary work.

Apart form it being way to agressive (and thus, slowing things down), it
also caused a re-slice to be done when a printer was connected with another printer.
We don't need to inherit from QObject if we expose the name elsewhere. This prevents having workarounds for C++ vs QML ownership, and also allows us to test this while mocking out CuraApplication.
Done during Turbo Testing and Tooling.
- Approximate diameter needed to be a string.
- GUID-tag is mostly in capitals.
- Workaround for an overload of 'get' not being called (default parameter didn't work somehow?).
part of CURA-6817
... instead of crashing.
Not _really_ part of a ticket, but I'm solving this now because otherwise I can't even _reproduce_ the steps for the bug in CURA-6807
