Corrected logic to set test webserver ENV variables

Initially, was setting them in the if block if ENV variables already existed.
It wasn’t being set as if condition was being evaluated as False.
But if condition should be mainly to store existing values.
In any case, test values must be set, hence moving it outside if block.
