Fix flaky test on Windows CI

[fflaten]

PR Summary

Fixing a flaky output test because Windows might use seconds and not milliseconds.

Includes minor cleanup in output to remove whitespace between time and time suffix. Future PR should consider extracting Get-HumanTime from Output.ps1 to Pester.Utility.ps1 to get consistency.

@nohwnd Thoughts? Any reason to keep some output hardcoded to milliseconds, or should I implement?

[nohwnd]

We are probably already outputting human time in all the normal output, in the diag logs I am okay if it stays using just ms. Less overhead (no function call) and less complicated to write the message.
