Fix locale-dependent test case.

Browse Source 
psql parses the interval argument of \watch with locale-dependent
strtod().  In commit 00beecfe8 I added a test case that exercises
a fractional interval, but I hard-coded 0.01 which doesn't work
in locales where the radix point isn't ".".  We don't want to
change this longstanding parsing behavior, so fix the test case
to generate a suitably locale-aware spelling.
