sql: deflake TestPerfLogging

[rytaft]

This commit deflakes TestPerfLogging by ensuring that test cases
that should not produce log entries do not match with unrelated log
entries and thus cause the test to fail. This is ensured by making
the regex more precise for the specific test case.

Fixes #74811

Release note: None

Encountered an error creating backports. Some common things that can go wrong:

1. The backport branch might have already existed.
2. There was a merge conflict.
3. The backport branch contained merge commits.

You might need to create your backport manually using the backport tool.
