webview context is not set when clicking link in messages tab Query Results pane

[Benjin]

Repros on latest main (6ce4498)

Repo:

1. Connect to a database and open a new query tab
2. Run a query, e.g. PRINT 'test'
3. On the messages tab of the results pane, click the line number link

Expected:

• print statement is highlighted in editor

Reality:

• nothing highlighted
• Console has error:

TypeError: Cannot read properties of undefined (reading 'queryRunner')
    at SqlOutputContentProvider.editorSelectionRequestHandler (c:\Users\me\Source\vscode-mssql\out\src\models\sqlOutputContentProvider.js:93:13)

After some investigation, it appears that the context in the link callback handler is set to the empty state version, not the correct state for that URI. Interestingly, the context is correct when the React is getting constructed.
