    tab: Remove tab before unreffing the loading_task data
    
    When there is a problem opening a file, if the user decides to dismiss the tab
    clicking the 'x' button in the info bar, remove the tab before unreffing the
    loading_task data. Failing to do so will likely result in an access to invalid
    memory.
