Un/Remapping keys requires disabling the hydra hint

[GCBallesteros]

Hydra will check that the key mappings are consistent with they hint box that it shows. If they are not everything breaks down. This means that if a key mapping gets modified by the user it will become inconsistent with the hard coded hydra hint and this plugin won't work. The solution is to disable the hydra hint.

To fix this we would need to generate the hydra hint on the fly based on the mappings available or ask the user to provide its own hint.
