If !img.complete, createPattern() should simply return null.

Proposed patch

Note the lack of test due to a bug in HTMLImageElement's complete attribute.
This will be addressed in a subsequent patch.

Oops! Turns out there IS a way to create an incomplete image and an existing test already covered it.
Updated patch with corrected test and ChangeLog.

Updated patch as per our discussion on IRC.
Test is now more verbose about what it's testing.
