### What problem does this PR solve?
Issue Number: None
Problem Summary: The system rowsets regression used a second-level current
timestamp captured after the test table was created as the lower bound for
`NEWEST_WRITE_TIMESTAMP`. If the table creation rowset was recorded just before
that lower bound, the timestamp filter could drop the initial rowset and make
the expected version list unstable. Capture a timestamp before creating the
table and move it slightly earlier, so the test still exercises the timestamp
filter while avoiding the boundary race.
