Livesync exception fix

[Cselt]

If you run your app with livesync then the second run will fail with an exception:

JS: Unhandled Promise rejection: Error in modules/login/login/login.html:null:null caused by: Cannot convert undefined or null to object ; Zone: angular ; Task: Promise.then ; Value: Error: Error in modules/login/login/login.html:null:null caused by: Cannot convert undefined or null to object TypeError: Cannot convert undefined or null to object

This can be fixed by deleting line 40 in fonticon.service.ts.
