Fix TIS/TSM in logs

[simons-public]

Silences the "is calling TIS/TSM in non-main thread environment" messages in the log when running a MacOS server as it is a red herring that causes a lot of issues to be filed. The messages are silenced by setting the OS_ACTIVITY_DT_MODE environment variable to NO.

Example issues that include mentions of TIS/TSM where it was not an issue:
#643, #599, #563, #532, #393, #232, #212, #112

This error comes from text input being handled by barriers which is another thread from the main barrier application. More info about Text Input Manager (TIS) & Text Services Manager TSM can be found here

Looks fine to me -- The only thing I'd question is the comment you put. What did you mean Silence "? Looks like a bit of a typo?

@shymega The is calling TIS/TSM in non-main thread environment log entries is what's being silenced. I realize it reads a little weird, would you like me to reword it?

No, don't worry, I misread it. My monitor is a bit washed out at the moment!

Looks alright to me though. I'll merge it now, cheers.
