psql now shows zero elapsed time after an error

Example (you need up-to-the-minute HEAD for this particular test
case, but anything that runs a little while before failing will do):

regression=# \timing
Timing is on.
regression=# select * from generate_series('2022-01-01 00:00'::timestamptz,
'infinity'::timestamptz,
'1 month'::interval) limit 10;
ERROR: timestamp out of range
Time: 0.000 ms

That timing is wrong. It visibly takes more-or-less half a second
on my machine, and v14 psql reports that accurately:

regression=# \timing
Timing is on.
regression=# select * from generate_series('2022-01-01 00:00'::timestamptz,
'infinity'::timestamptz,
'1 month'::interval) limit 10;
ERROR: timestamp out of range
Time: 662.107 ms

While I've not bisected, I think it's a dead cinch that 7844c9918
is what broke this.
