libview: fixing memory leak
The memory leak was caused by a g_signal_connect which was never disconnected. This patch makes sure the signal is disconnected and the job is cancelled before creating another rendering job. It additionally introduces a helper function to cleanly finalize the job. origin commit: https://gitlab.gnome.org/GNOME/evince/commit/939c434
