New version of party package doesn't export ctree_memory

[larskotthoff]

A new version of the party package was released today. We're seeing test failures for the mlr package with mboost learners because of that:

'ctree_memory' is not an exported object from 'namespace:party'
...
15: mboost::blackboost(f, data = getTaskData(.task, .subset), control = ctrl, tree_controls = tc, 
       family = family, ...)
16: mboost_fit(bl, response = response, weights = weights, ...)
17: lapply(blg, dpp, weights = weights)
18: FUN(X[[i]], ...)
19: dpp.blg(X[[i]], ...)
20: object$dpp(weights)
21: party::ctree_memory
22: getExportedValue(pkg, name)
23: stop(gettextf("'%s' is not an exported object from 'namespace:%s'", name, getNamespaceName(ns)), 
       call. = FALSE, domain = NA)

Should be solved on github already (see ddef62a). However, testing and upload of a new mboost version to CRAN will take some more time.

Thanks, I can confirm that this fixes our tests.
