[FIX] web_tour: tour tip does not open

When mouse hover on tour droplet, it shows tip information but when click on
app name(ex- expenses) and hover on tour droplet, it does not shows tip
information, it is because tip is now part of o_content element i.e. controller
element and when we click on app name it re-renders whole action manager and
due to which tip element also removed and later tip element added but new tip
insteance is not created, element of existing tip instance is added to DOM and
due to which event bound on previous element is not bound on new element, to
fix this we need to explicitly bind events on tip.

after this commit: tip shows information even after clicking on app name as we
explicitly bind events when tip is re-rendered.
