Fix WeakPtrFactory member placement in ipc

Fix WeakPtrFactory member placement

Changing in the intialization order of WeakPtrFactory in src/ipc module
such that all member variables should appear before the WeakPtrFactory
to ensure that any WeakPtrs to Controller are invalidated before its members
variable's destructors are executed, rendering them invalid.
