Prior to this change we attempted to push translations made direclty in
the git tree to transifex allowing translations to be made via git
directly or in transifex. Simplify the process to avoid cases where the
transifex client will refuse to update local translations because they
are newer than those in transifex. This makes transifex the only source
of translation updates. In addition to simplifying the process force tx
pull -a operations as a way to force the updates if we end up in this
state.
