3 fixes where global-config as incorrectly called for non desktop

These issues were introduced with #6531. The global-config component
should not be called if not in a supported platform. This fixes
re-index, switching graphs and editing config.edn for mobile.  Switching
graphs was partially fixed in #6664 but didn't address the root cause
which is the global-handler component shouldn't be called if not enabled
for a platform
