unclutter continually restarting

[alunduil]

Issue description

After enabling unclutter via the service module (services.unclutter.enable), I find that it errors due to an incorrectly specified display parameter and simply continually restarts.

The journal entries:

Restart=always
RestartSec=3

I'm pretty sure there is a symbol conflict causing the display to be an unadorned colon but I am not sure.

Steps to reproduce

1. enable unclutter—services.unclutter.enable
2. observe running unclutter's behavior

Fixed by c91c320 in master. I suppose we can pick that to release as well.

The fix should be included in the next release channel update.
