Different Style of Error When Trying Create Channel With Non-Unique Name

[LeoNerdoG]

If user tries to create a channel with a non-unique name in Wire Graph, Kura shows an error, which is OK, but the error style is like no other in the UI (see screenshot bellow). Usually when user does something wrong Kura opens a new error window which is not the case here.

Testflow:

1. Login to Kura as admin/admin
2. Go to packages, install wires-development-package
3. Go to Wire Graph and create a wire asset with a channel "channel-1"
4. Try to create another channel with the same name
5. Observe the error thrown by Kura

Expected behavior Error styling shoud be the same as for all other errors in UI.
