NoProfile in ToolTaskThatTimeoutAndRetry test (#8659)

This failed for me in an unrelated PR and on my dev box and at least on my dev box it was because sometimes my PowerShell profile took longer than 1 second to process.

Pass -NoProfile to avoid that time entirely when it's not necessary.

In addition, save the engine's log to the test log to give some clues if the test fails again.
