Fix truncated strings when loading and storing emblems (bug #7171).

The last character of all key names was always left out when storing the
key/value pair in the TDB file. As a consequence, two similarly named
files (e.g. x1 and x2) were treated the same (x) and both were assigned
the same emblems.
