Error handling in Create Recipe for duplicate names

[KKoukiou]

This should be handled like this in the future:

The blueprints list should be updated dynamically with events, and this should be passed to the Modal as a property. Once it changes the property will change and the modal will re-render.
If the name we have inserted matches an existing name, the warning will appear automatically.

Calling the API to list blueprints inside the modal dialog code it defiitely a no-go.

@jgiardino since we don't have yet events, I would close this issue, since the current implementation is not that problematic.

The issue will solve itself once we have events introduced.
