Merge lp:~sylvain-pineau/checkbox/fix-1561821 into lp:checkbox

[Sylvain Pineau]

Fixes the linked bug, but without modifying the udev parser to add an extra input-id field.

[Pierre Equoy (pieq)]

It's very smart!

When I was testing it and checking how it worked, I realized there are other jobs where we need to remove the {path} parameter in the description or else it will fail the same way:

  - suspend/pointing-after-suspend_{product_slug}_{category}_{__index__}
  - suspend/clicking-after-suspend_{product_slug}_{category}_{__index__}

Other than that, it looks great. Thanks!

providers:checkbox: Remove {path} requirement in input jobs

As those may change if the same device is unplugged/re-plugged
(even on the same port).

I've fixed the suspend jobs
