Configured icon is being overwritten

[golles]

Hi, I migrated my config to support the new version and I'm now using icons in the yaml (before I did by customizing).

I copied Lifeliner config from an other issue (it flies over my house quite often) and just noticed that the helicopter icon changed into an ambulance.

config:

  - platform: p2000
    name: P2000 Lifeliner 1
    icon: mdi:helicopter
    regios: 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25
    capcodes: 0120901
    scan_interval: 60
    nolocation: True

I personally find if an icon is defined, it should not get overwritten. Hence this bug report
