test(ngRepeat): move an existing test into the right describe block
test(animateSpec): remove unused variables
chore(testabilityPatch): fix the dump fn so that it works with karma's debug.html
fix(ngRepeat): preserve original position of elements that are being animated away

During the recent refactoring a typo was made that broke code that detects if we are
already removed from the DOM (animation has completed).
