Amend the way to invoke message application for the the first time satellite connected notification

It was finalized to invoke the home screen of default message app instead of invoking 'What to expect' dialog, as OEM's message app may be default.

Bug: 322733285
Test: manually tested with below scenario
      1. Google message is the default app.
      2. Playstore downloaded app is the default app.
      3. No default app is decided.
