[nautilus] location-entry: Allow white space padding

[Ernestas Kulik <ernestask src gnome org>]

commit e76cfc99855dafc2bfc46e0544f5818653ce46c6
Author: Daniel Pauls <daniel1708 de+git gmail com>

    location-entry: Allow white space padding
    
    If a path in the location entry has white space as a padding Nautilus
    will throw an error.
    Stripping it before parsing will fix this.
    
    Fixes https://gitlab.gnome.org/GNOME/nautilus/issues/1030
