fix(PWA): post login redirection fails due to default_route conflict with other app (backport #2351)

[mergify]

When hrms and gameplan are installed on the same site, post login redirection fails because gameplan has an on_login hook return to navigate to /onboarding

and hrms tries to route to default route - so it ends up routing to /hrms/onboarding
