Widget stuck on "Loading" forever after entering "02104"

[morganwahl]

Overview:

Typing 02104 in the widget input and pressing "enter" causes the widget to just say "Loading" forever. Putting a new zip code in and hitting "enter" doesn't cause the new search to be made, it just stays on "Loading".

I suspect 02104 is not a real zip code. I entered it on accident.

Acceptance Criteria:

Entering a non-existant zipcode doesn't cause "loading" forever.

Bonus points:
Submitting a new zipcode restarts the lookup process, even when in the "Loading" state.
