Bug: Setting $location.search() param value to null causes infinite digest loop

[Antontelesh]

The bug occures only in new 1.3.0 version of Angular.
When I use $location.search('some_param', 'value') everything works fine.
But when I then use $location.search('some_param', null) to clear that search param, Angular falls into infinite digest loop.

See plunkr for example.

I believe this is a legitimate bug, unfortunately it's difficult to reproduce in a unit test, because $$checkUrlChange is noop'd --- fixing this is probably blocked on #9527 --- I will try to hurry up and get that working
