@rafael added this in 971d0bb7 (erp5: Make possible extent the list of
initial business templates to install), but we dropped that change while
merging erp5-cluster to master - see:

    6bbb61a8 "Merge branch 'master' into erp5-cluster", and
    e84d5e83 "Merge branch 'erp5-cluster'"

6bbb61a8 claimed that it

    Dropped commit 971d0bb7
    ("erp5: Make possible extent the list of initial business templates to install").

but it actually dropped changes only under stack/erp5/ , not software/wendelin/

Fix it.
