Fixes s__spy_spyOn override warning

Opening jasmine spec file caused this error. Duplication? Anyway deleted second one.

    Warning: /Users/iwanaga/dotfiles/vimfiles/bundle/jasmine.vim/snippets/jasmine.coffee.snippets:201 is overriding `s__spy_spyOn` from /Users/iwanaga/dotfiles/vimfiles/bundle/jasmine.vim/snippets/jasmine.coffee.snippets:199
    Please rename the snippet name or use `delete s__spy_spyOn`.
