stream-clone-test: simplify bookmark clone

The important things to test here is the number of file included (to catch that
the bookmark file was sent). So we keep that part non glob'ed but glob the
rest.

The glob'ed numbers are very fragile and consume a lot of time for little value
when adjusting formats, caches, and protocol.

Check upgrade behavior
======================

Right now, sidedata has not upgrade support

Check that we can upgrade to sidedata
