Voron Switchwire

How to reproduce

1. Set printer minimum_retraction_travel to 0.
2. Create a printer profile and set spiral_mode to true. (Yes to automatic setting update for walls, top, etc)
3. Slice a primitive.
4. Observe flow visualiser and see high flow rates on a pseudo-seam.
5. Set printer minimum_retraction_travel to >= 1mm.
6. Observe correct spiral vase behaviour and acceptable flow rates.

Actual results

With minimum_retraction_travel to 0.

Observe flow rates much higher than expected.

Expected results

Ideally, when setting spiral vase mode this setting should be set to a value greater than 0 automatically or a dialogue should appear to warn the user of unexpected behaviour if this is 'intentional' with a zero value minimum_retraction_travel.
