Fix duplicate printing of thread info when debug is enabled

[mairooni]

Description

This PR fixes the duplicate printing of thread information. When both the flags for debugging (--debug) and thread info (--threadInfo) were enabled, the thread information was printed twice. In this PR, the thread information is printed only if the debug flag is not also enabled.
