MainDeployer knows that it is doing a redeploy(), the problem is just
that the redeploy() should also be in the TomcatDeployer or that
MainDeployer should tell to the TomcatDeployer that the undeploy() is
called for a redeploy() (like undeploy(false) for a redeployement and
undeploy(true) for an undeployement).
