Don't write trace summary report in response to wp-admin/?health-check-test-wp_version_check=1

[bobbingwide]

While running the health-check plugins tests I was getting
A plugin has prevented updates by disabling wp_version_check()

It turns out that the test_wp_version_check_attached function is rather sensitive to the reply it receives
to the following request.
wp-admin/?health-check-test-wp_version_check=1

• It only expects a reply of yes
• It can't handle the HTML comments returned by oik-bwtrace.

Workaround fix for oik-bwtrace

update bw_trace_ok_to_echo() to return false when the query parameter health-check-test-wp_version_check has been passed.
