Workaround issue of synchronisation in nightly build of FunctorCache
In the 2018-patches
nightly, the FunctorCache build fails very frequently due to
File "Rec/BrunelCache/options/Brunel.py", line 13, in <module>
from Configurables import Brunel
ImportError: cannot import name Brunel
This MR provides a workaround. It's not clear why this only happens in 2018-patches
