bundle2: make it possible have a global transaction for the unbundling
We use the `gettransaction` method approach already used for pull. We
need this because we do not know beforehand if the bundle needs a
transaction to be created. And (1) we do not want to create a
transaction for nothing. (2) Some bundle2 bundles may be read-only and
do not require any lock or transaction to be held.
