shelve: be quiet when unshelve pulls from the shelve bundle unshelve was quite verbose and it was hard for a user to follow what really was going on. It ended up saying 'added 1 changesets' ... but the user just expected and got pending changes and never saw any changeset. The use of bundles is an implementation detail that we don't have to leak here. Pulling is quite verbose, optimized for pulling many changesets from remote repos - that is not the case here. Instead, set the quiet flag when pulling the bundle - not only when temporarily committing pending changes. The 'finally' restore of ui.quiet is moved to the outer try/finally used for locking.
