Fix issue with shallowEquals incorrectly returning too early

[ice1080]

shallowEquals has a minor bug in it that causes it to return too early if a prop has an equals method on it. This means that the order that props are defined causes them to change the rerender behavior (e.g. if prop 2 changes but prop 1 doesn't change, shallowEquals says they are the same and things are not rerendered).

The comment above the for loop says all keys, so it should loop through all keys before returning that objA and objB are equal. Change the method to return false if props are unequal, otherwise finish the loop before returning true.

Note that this is a minor fix until @abstrakt8 has time to work on #298 , as the changes in that also fix this bug
