phoneuid-dbus: fix incorrect g_bus_own_name_on_connection usage

g_bus_own_name_on_connection was used with syntax from g_bus_own_name,
resulting in all callbacks being mismatched (_on_bus_acquired was called
when name was acquired, _on_name_acquired when name was lost, and _on_name_lost
was lost in ethernal chaos), causing first call right after phoneuid appeared
to fail.

This should properly fix SIM PIN issues (#1478, #2094, #2095, probably even more).
