    um-utils: Remove incorrect NULL check
    
    g_utf8_next_char(p) returns a pointer to the next UTF-8 character in the
    given string. This is always p + n for a small constant n.
    
    Assuming p points to a well-formed, 0-byte-terminated UTF-8 string, p +
    n is always non-NULL. And GCC warns about this:
    
        ../gnome-initial-setup/pages/account/um-utils.c: In function 'extract_initials_from_name':
        ../gnome-initial-setup/pages/account/um-utils.c:520:47: error: the comparison will always evaluate as 
'true' for the pointer operand in 'p + (sizetype)*(g_utf8_skip + (sizetype)*(const guchar *)p)' must not be 
NULL [-Werror=address]
          520 |         if (p != NULL && g_utf8_next_char (p) != NULL) {
    
    I think the intention here is to check if *(g_utf8_next_char(p)) is not
    (char) 0. This is guaranteed by the use of g_strstrip() above: the
    string does not end with whitespace. But it also wouldn't matter if it
    were: g_string_append_unichar (initials, 0) would just append a
    redundant NUL terminator.
    
    Remove the unnecessary check.
