Subject: [PATCH 1/2] Do not pass -v to the test runner for the global verbose
 flag

The global verbose flag is also set by --trace and -n, so deriving the
test runner's -v from it leaked -v into the test process ARGV and broke
apps that inspect ARGV at load time. Keep echoing the command for the
global flag, but base the -v injection only on the task's own @verbose.

Fixes #732

Subject: [PATCH 2/2] Make captured_test_command a private test helper

It is a helper, not a test case, so keep it under private like the
other helpers in the test suite.
