Broken appStateService in the IDE

[kittaakos]

Describe the problem

The FrontendApplicationStateService is a Theia service that can pause the execution logic and wait until a particular application state ('init', 'ready', etc.) is reached. Then, the IDE can perform various logic. The app state service throws an error at IDE startup.

To reproduce

Steps to reproduce:

• Download the latest nightly,
• Start the IDE,
• Open DevTools (to see the error),
• See the error.

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'reachedState')
    at H.init (arduino-frontend-contribution.tsx:241)

Expected behavior

The app state service does not throw an error and can be used to wait until a specific app state is reached.

As noted in the PR, the broken injection has a side effect.

Steps to reproduce:

• create a new sketch and save it to your local sketchbook,
• open a terminal (can be from IDE too),
• create a new .ino file from the terminal,
• Expected: the new .ino file opens in a tab in the IDE,
• delete the .ino from the terminal,
• Expected: the deleted tab closes in the IDE.
