[pitivi] tabsmanager: Use the same config sections under all locales

[Alexandru Băluț <alexbalut src gnome org>]

commit 9897ad51c27796ccac5ce9805ff0abe2f078926c

    tabsmanager: Use the same config sections under all locales
    
    Using translated strings for config section names leads to encoding
    problems.
    
    The config sections are only for advanced users, having them always in
    Eenglish should not be a problem.
    
    Fixes #2157
