[Evohome] EvohomeAccountBridgeHandler.checkInstallationInfoHasDuplicateIds

[mossc001]

Expected Behavior

Post login, status changes from 'INITIALIZING' and discovers Evohome zones/devices.

Current Behavior

• Evohome binding is installed via PaperUI.
• Thing is created using PaperUI and login details are entered and saved.
• Status of thing gets stuck on 'INITIALIZING'.

Logs display the following which I'm unable to resolve:
