[PATCH 07/15] merge-recursive: fix memleaks

Usually when using string lists it looks like:
    struct string_list a = STRING_LIST_INIT_NODUP;
    // do stuff with a such as
    string_list_insert(&a, "test string");
    print_string_list(&a, "test prefix");
    // Cleaning up works on everything inside the struct, not on the
    // struct itself:
    string_list_clear(&a);

But as we deal with the pointers to the string lists directly, we also
need to free the actual struct.
