I noticed that the CogVM job on build.squeak.org is failing. It turns out
that the Squeak script is failing because of this:

Installer ss project: 'Speech' ==> MessageNotUnderstood: MCHttpRepository>>removeRepository:

InstallerMontecello>>project: expects to work with a MCRepositoryGroup, not
with a single repository.

Reverting to the prior Installer-Core version fixes it, but I'm not sure if
that's the right thing to do. Perhaps InstallerMonticello>>project needs to
be fixed instead?
