Upgrade from 1.4.2 to 1.4.3 causes jasmine tests to fail

[sansthesis]

I'm going to try to get a test case this weekend, but I don't know if I will be able to reproduce the environment.

My karma/jasmine unit tests pass with ampersand-collection 1.4.2 but time out 100% of the time when using 1.4.3. I think that the reindex code is hitting an infinite loop or is causing too many cascading operations.

@lukekarrys can you look at this when you get a chance - the merge for 1.4.3 shows only a single PR since 1.4.2

@JasonRose I will look into this also. Thanks for pointing us the in right direction with the infinite loop + cascading operations stuff. Both those things would make sense with how the new index code works I think.

Fixed in 1.4.4
