fix rspec failed tests

Hello , bootstrap fans!
When I run rspec on current master I have the following errors, so fix it changing disposition of html attributes in elements(which is not important in real practice)

twitter-bootstrap-rails$ rspec

@seyhunak , it looks really strange that travis failed in 2.1.1, but in 2.1.5 and 2.1.1 ruby rspec are completed successfully
