Fix change to default colors in job log

What does this MR do?

In #36335 (comment 250471967) a customer reported that color changes in their job log was incorrect. It turned out that we missed changing ANSI colors to default values when [39m code is encountered for the foreground and [49m code is encountered for the background.

Expected behavior is:

1. if job log contains [39m reset the foreground color from any values that was set before
2. if job log contains [49m reset the background color from any values that was set before
