1. Click on "Add PostGIS Layer"
2. Click on "New Connection"
3. Call the new connection "test/1"

Expected behavior: on creating the connection, there's a new "test/1" connection shown in the connection selection widget.
Obtained behavior: the connection selection widget has just a "test" connection

Further steps:

4. Click on 'Add PostGIS Layer"
5. Click on "New Connection"
6. Call the new connectoin "test/2"

Expected behavior: there are now 2 connections
Obtained behavior: there's still a single connection, still only named "test"

Further steps:

7: Create a new connection, calling it "test/1"

Expected behavior: as there's a single connection, called "test", I'd now expect "test/1" to be created
Obtained behavior: the GUI complains that "test/1" already exists (but isn't shown)

So basically I'm left with a single "test" connection shown in the connections list but QGIS really knows about "test/1" and "test/2" enough that I cannot use those as names for new connections.
