make vips_image_write() sever connections
...
when writing to a non-partial image, vips_image_write() now carefully severs
all connections between the two images on completion
this fixes a couple of cases where we had bad behaviour: writing to a
temp file could leave dangling pointers, see
https://github.com/jcupitt/libvips/issues/708
and writing to a memory buffer during copy_memory coud leave dangling
pointers too, see:
