nobled eb906d85ca tests: abort if clutter_init fails
This fixes segfaults when something goes wrong during
init, but the test keeps going anyway.

Except for test-easing and test-picking, these were fixed by
sed magic:

sed -i -s -e "s/clutter_init \?(&argc, &argv)/\
if (clutter_init (\&argc, \&argv) != CLUTTER_INIT_SUCCESS)\n\
    return 1/" tests/*/*.c
