Ensure that filespace hostname is duplicated before freed
Ensure that filespace hostname is duplicated before freed

Before freeing the CdbComponentDatabase struct we need to copy the
hostname member since we are passing that to the QE's. Should the
memory be reclaimed before the command is serialized to be passed
down the hostname part will contain rubbish and either not work or
crash the backend.
