Multiple click event handlers bound to withdraw tab

Problem/Motivation

When using the withdraw button a click handler is bound to .eu-cookie-withdraw-tab everytime the button is pressed. When the animation time is set to 0 the banner cannot be opened, because the toggleWithdrawBanner function is called twice and closes the banner immediately.

Steps to reproduce

• Use following settings:
  

  method: 'opt_in'
  withdraw_enabled: true
  settings_tab_enabled: true
  popup_delay: 0

• Click "No, thanks"
• Click "Privacy settings"
• Look at events on .eu-cookie-withdraw-tab:
  

  jQuery._data( jQuery(".eu-cookie-withdraw-tab")[0], "events" );
  Object { click: (2) […] }

Proposed resolution

Do not bind the click handler in declineAction.
