Applied comm-central workaround: https://hg.mozilla.org/build/buildbot-configs/rev/c638c6f30ea0

Comm-aurora is affected too.

Ported to aurora in  https://hg.mozilla.org/build/buildbot-configs/rev/432486a808e3

Do we need to port back the workaround for comm-beta builds of Lightning 2.0?

Ported to beta too just in case, I'm working on the 2.0b1 builds.
