Fix segfault with bad setting in the Image node.

Browse Source 
The limit in the UI tooltips to set the amount of
images used in animation allow the zero value,
that cause a segfault.

This commit fix the UI, add a init value of 1 to
the node and also check in case that
node_composit_get_image return NULL.
