[BUG] Navclean cron error

[Zotan]

Describe the bug

Since upgrade to 5.9 the navclean cron job causes a python exception:

Cron navcron@nav navclean -f -q --netbox --websessions
Traceback (most recent call last):
File "/usr/bin/navclean", line 8, in
sys.exit(main())
TypeError: main() missing 1 required positional argument: 'args'

To Reproduce

Upgrade to NAV 5.9

There is a chance that this might have occurred before the upgrade as because of a server move our NAV instance has been down since mid Feb. I did the update today as part of bringing it back on line.

Expected behavior

Cron job should not cause a python exception.

Environment (please complete the following information):

Nav 5.9 on Debian Buster from packages

Thank for the bug report, @Zotan. This is easily reproducible, but it wasn't flagged by our test suite because it executes the NAV scripts in a slightly different fashion from fully installed scripts.
