    Here's some experiments about `ParagraphIT` error,
    
    - It passes on my local machine with firefox 31.0 (the same version with 
travis uses)
    - It passes on my travis account, constantly
    - It fails on apache travis account, constantly
    
    And i tried narrow down what cause the error on apache travis account, and 
in case of `ParagraphActionIT.testCreateNewButton`, it opens paragraph's 
setting dropdown menu successfully,

    And i believe it locates `Inserts New` button and click(), but nothing 
happens and test fails.
