phase: add a transaction argument to retractboundary
We now pass a transaction option to this phase movement function. The
object is currently not used by the function, but it will be in the
future.
All call sites have been updated. Most call sites were already enclosed in a
transaction for a long time. The handful of others have been recently
updated in previous commit.
