Unable to save profile with connection string + Enable Trust Server Certificate

[cheenamalhotra]

• MSSQL Extension Version: main
• VS Code Version: Latest
• OS Version: Windows 11

Steps to reproduce:

1. Create a new connection with connection string (that triggers Enable Trust Server Certificate error)
2. Click on Enable Trust Server Certificate

Below error is captured in Extension Host and OE tree fails to load:

stack trace: TypeError: Cannot read properties of undefined (reading 'length')
    at getConnectionDisplayString (c:\Users\cmalhotra\Code\GitHub\vscode-mssql\src\models\connectionInfo.ts:150:11)
    at Object.getPicklistDescription (c:\Users\cmalhotra\Code\GitHub\vscode-mssql\src\models\connectionInfo.ts:114:25)
    at ConnectionStore.createQuickPickItem (c:\Users\cmalhotra\Code\GitHub\vscode-mssql\src\models\connectionStore.ts:389:26)
    at c:\Users\cmalhotra\Code\GitHub\vscode-mssql\src\models\connectionStore.ts:469:36

Issue occurs as conn string is not updated properly, and profile is saved also by itself - in connection string format.

Mitigation:
Use Connection properties instead
