Enable the setUp() function for every type of test

[gustavo-grieco]

This small PR is testing to enable the setUp() for every type of test (not only dapptools). It will be always executed, if available if it will still be part of the ABI so it can be re-executed at any time (therefore, it must be idempotent).

Is setUp() function a good place to call "initialize" for openzeppelin upgradeable contracts?
