Adding connection caused previous connect to disappear from Connections view

[kburtram]

Steps to Reproduce:

1. Add a connect to one server and use it for a while, running queries, using context menus, etc.
2. Add a connect to another server in the same session.

Note: this likely isn't a consistent repro, so we should try to understand how this code happen from code inspection or additional logging, or something approach to locate and resolve this harder to repo issues.

Expected: Two connections in the Connections view.

Actual: The new connection shows up and the old one is gone. Looking in the settings JSON both connections are still there.
