gapplication: Guard g_application_mark_busy()

Browse Source 
The `GApplication` must be registered before calling
`g_application_mark_busy()`. Document that, and add a guard.

The same is true for `g_application_unmark_busy()`, but the existing
documentation and guard for `busy_count > 0` are enough.
