Infinite rerender caused by nested components rendered from an ObserveArray

[imaustink]

There seems to be a problem when rendering nested React components from a can-observe array when updated asynchronously.

Failing test here: https://github.com/bitovi/ylem/pull/159/

See comments in the test for more potentially useful details.

@BigAB @christopherjbaker @DesignByOnyx @justinbmeyer thanks for helping me track this down and find a workaround, fellas.

This is fixed due to #165 and #151, but I have been having some trouble re-creating it reliably, so I am waiting for @imaustink's assistance before I mark it as closed.
