Problem Statement/Rationale

What is going wrong? What action would you like the Engineering team to take?
A new connection without URL can be saved to favorites but won't appear on the sidebar. A user can still connect and later see the saved connection after logging out and even use it to login (the default `mongodb://localhost` URL will be saved for such favorite).

Steps to Reproduce

How could an engineer replicate the issue you’re reporting?
On the connection form:

• click new connection
• click favourite banner, add name and save it
• favourite is being saved but doesn’t appear in the sidebar
• click connect and then disconnect
• favourite is on the sidebar

Expected Results

What do you expect to happen?
We either do not save empty connections to favorites, or we update the sidebar respectedly.

Actual Results

What do you observe is happening?
The favorite is not displayed immediately, only after disconneting.
