the `throw-space-n` shortcut definitions in amethyst.yml are seemingly ignored

[gplusplus314]

Describe the bug

I have settings and shortcuts defined in my amethyst.yml. They all work, except the throw-space-n shortcuts aren't set to my custom ones and revert back to the equivalent of mod2-n. My keybinds are intentionally zero-indexed, meaning 0 is space 1, but the shortcuts aren't being respected.

See reproduction and screenshot section.

Applications:
All

To Reproduce
Here is a snippet from my ~/.config/amethyst/amethyst.yml:

mod1:
  - control

mod2:
  - control
  - shift

throw-space-1:
  mod: mod2
  key: 0
throw-space-2:
  mod: mod2
  key: 1
throw-space-3:
  mod: mod2
  key: 2
throw-space-4:
  mod: mod2
  key: 3
throw-space-5:
  mod: mod2
  key: 4
throw-space-6:
  mod: mod2
  key: 5
throw-space-7:
  mod: mod2
  key: 6
throw-space-8:
  mod: mod2
  key: 7
throw-space-9:
  mod: mod2
  key: 8
throw-space-10:
  mod: mod2
  key: 9

Expected behavior
Keyboard shortcuts in amethyst.yml should be respected.

Additional context
This might be related to #1521 .

If I go through the GUI and manually delete, then rebind the keys, they work. But when Amethyst restarts, everything reverts and it matches the screenshot from above, breaking my configuration.
