gdbusinterfaceskeleton: Fix a use-after-free of a GDBusMethodInvocation
This GDBusMethodInvocation
may be shared across threads, with no
guarantee on the strong ref in one thread outlasting any refs in other
threads — so it needs a ref in this helper struct.
This should fix a use-after-free where the GDBusMethodInvocation
is
freed from g_value_unset()
after g_signal_emit()
returns in
dispatch_in_thread_func()
in one thread; but then dereferenced again
in g_source_destroy_internal()
from another thread.
