Fix SIGSEGV in InfoPipe startup
If the user that starts InfoPipe is not permitted by the system bus to request the InfoPipe name, the sssd_info process would segfault, since the destructor for the connection object was called before it was completely created. I have moved the initialization of the destructor to later in the setup routine.
