#skipOnPharoCITestingEnvironment seems to not work on WIN and MAC

[MarcusDenker]

Bug description testJobIsFinishedWhenWaitingMoreThanWorkBlockDuration is failing on win even thought it does

" self skipOnPharoCITestingEnvironment."

This is related to environment variables:

onPharoCITestingEnvironment
	
	^ Smalltalk os environment at: 'PHARO_CI_TESTING_ENVIRONMENT' ifPresent: [ true ] ifAbsent: [ false ]

[MarcusDenker]

on MAC, too:

SpJobListPresenterTest>>#testJobIsFinishedWhenWaitingMoreThanWorkBlockDuration

was failing even though it is skipped

[MarcusDenker]

What is odd: if skipOnPharoCITestingEnvironment would not work, we should see much more tests failing.

[MarcusDenker]

I checked the CI: the variable was not defined globally, I added it back

[MarcusDenker]

Still not working correctly

[MarcusDenker]

After adding it to the global config had no effect, I added the environment variable to all the CI machine runner setups

[MarcusDenker]

The test testJobIsFinishedWhenWaitingMoreThanWorkBlockDuration does not have #skipOnPharoCITestingEnvironment...

so it seems the mechanism works, but some methods miss the tag.
