Shape Detection: resolve with empty results if any input element's dimension is zero

Shape Detection: resolve with empty results if any input element's dimension is zero

This CL homogenises the behaviour of the ShapeDetector's
detect() in case of an input element with any zero dimension.
Assuming such input element pass the cross origin test and 
its underlying pixel data can be retrieved, then if either width
or height is zero, detect() Promise is resolved with an empty
array.

LayoutTests are adapted/extended/cleaned up.
