AttributeError: 'Blueprint' object has no attribute 'before_app_first_request'. Did you mean: 'before_app_request'?

Hi!

I updated ckanext-ldap to version 3.3.3, and now it seems that a Flask blueprint object is not working.
Any time I run a ckan command, for example

# ckan -c /etc/ckan/default/ckan.ini

I get this error:
