[tracker/wip/carlosg/several-fixes: 1/4] libtracker-data: Remove unused code

[Carlos Garnacho <carlosg src gnome org>]

commit f7cfc061354e29475d2e24c328d2adb1ad91ccf4

    libtracker-data: Remove unused code
    
    The function call is commented out since commit c65e02f479e30, as error
    tracking works slightly differently. The root field in the struct was
    actually unused and can go away.
