Remove Duplicate Entries for Doors and Trunk Locked Sensors.

This is how it looks before the fix:

@oliverrahner forgot to remove trunk_locked_sensor and door_locked_sensor from the dashboard.py.

It's probably not a good idea to remove them.
The error that I made is to not correctly adapt the supported checks: the *_sensor entities should be supported if remote lock/unlock isn't supported, the other entities if they are. So _sensor is the read-only entity, the one without is the read/write entity.
