stat: increment members counter after call to sum_thread_stats()

Increment ts->members after the call to sum_thread_stats(), just like how
it's done in client.c and gclient.c.

There is no reason why stat.c should increment ts->members before calling
sum_thread_stats(). Change stat.c so that it is consistent with client.c
and gclient.c. This way, sum_thread_stats() could actually make use of
ts->members (if it wanted to), since it is now being updated consistently.

No logical change, as currently, ts->members is only used in
show_thread_status_normal(), which is always called after the call to
sum_thread_stats().
