Fix Ajax option fail to error@JSONFixture.

When I tried to use getJSONFixture methods, it didn't work.
I'm using jasmine-jquery with jasmine-gem in RoR.

I think fail option for $.ajax doesn't seem to exist.

My env is like below.
jquery -> v1.9.1
jasmine jquery -> Version 1.5.0

But it's refixing of recent commit.
Here's commit No.
<fafeb7189e7c4bbded7b27d9ca83f0fac04fb32b>

see it.
