h2o.get_leaderboard function does not work for re-attached H2OAutoML object

[exalate-issue-sync]

I found this to be the case in R. I did not check Python, so that should be checked as well.

If you create an AutoML object, then disconnect the client, and then start a new R session and then reconect to the running H2O cluster – if you get the AutoML object and try to get the extended leaderboard using the h2o.get_leaderboard() function, it does not work.

{code:r}> aml <- h2o.get_automl("aml20") #created in a previous R session

lb <- h2o.get_leaderboard(aml, extra_columns = c("ALL"))
