No MagmaCommitError with two local sessions

[Giovanni Corriga]

Hi all,

the following snippet

session1 begin.
session1 root at: #foo put: #bar.
session2 commit: [session2 root at: #foo put: #baz].
session1 commit.

results in a MagmaCommitError, as it should, when the sessions are
remote and created with #hostAddress:port: , but runs successfully when
the two sessions are created using #openLocal: .

Is this expected, or is it a bug?

	Ciao,
