[tracker/wip/carlosg/coverity-fixes: 7/10] libtracker-data: Ensure an error is set

[Carlos Garnacho <carlosg src gnome org>]

commit 748acf48dd8a8cf4ed00ccf1c04093a7004db2ec
Author: Carlos Garnacho <carlosg gnome org>
Date:   Wed Mar 4 20:21:43 2020 +0100

    libtracker-data: Ensure an error is set
    
    If we fail to parse the DBus URI for SERVICE{}, we would bail out
    without an error, even though it's used for warnings. Ensure we
    have an error for that case.
