Extension commands do not work until js/ts file has been opened

[lucacasonato]

Describe the bug

The VS Code actions on the command palette provided by this extension do not work (error out) until the user has opened a JS/TS file in the workspace.

To Reproduce

1. Open a VS Code workspace with the extension disabled (no files open)
2. Open command palette and run Deno: Welcome
3. See this error: Command 'Deno: Welcome' resulted in an error (command 'deno.welcome' not found)

Expected behavior

The Deno: Welcome and Deno: Initialize Workspace Configuration options should always work, and all other commands should only be present in the command palette if the lsp has been started and is ready to receive commands.

Versions

vscode: 1.53.2
deno: deno 1.7.4
extension: 3.0.1

I will check if there is a way to activate the extension in more general scenarios.
