Crash in WelcomeOnboardingActivity

I found that crash in GPS in 1.50.41. I think we have it in stable channel as well, it needs to be fixed and uplifted.

Going to label this as QA/No as we'll basically verify this by default while running through verifications and reduced manual passes via the next 1.48x RC as the onboarding is always displayed on first launch and QA installs/launches Brave several times while running the builds.

The above requires 1.48.169 or higher for 1.48.x verification 👍
