Describe the bug

While attempting to reproduce #4127, I discovered that a specific order of operation crashes the printer. I believe that issue may actually stem from the same basic problem, which would be related to axes being (mis)marked as homed or filament (mis)marked as unloaded, even though they may not be.

While at first I ran the procedure as unload - stop - auto home - unload - stop, the first unload-stop has not caused a crash and I managed to remove it from the reproduction steps.

How to reproduce

1) Make sure filament is loaded and restart the printer 2) Run Control > Auto home 3) Run Filament > Unload filament 4) After X axis is homed to the right, press stop while the head is moving to the left 5) Printer becomes unresponsive (may happen after one press)

Even though I made it I somehow forgot about this issue until now, but it's very similar
