Update right side of Lokole email address

[c-w]

Previously, the email address appeared as username@iiab-box.lokole.ca.
With this change, the email address appears as username@box.lan

See #1293

This seems very low-risk so I'll go ahead and merge it.

Thanks all for continued testing!

Is there a way to reinstall a fresh version of Lokole on Internet-in-a-Box ?

FYI most IIAB apps allow you do the following: (to freshly install that IIAB app/service)

cd /opt/iiab/iiab
./runrole lokole

But when I do the above, email addresses remain as USERNAME@box.lokole.ca (instead of USERNAME@box.lan as I'd hoped!)

Is there a way to wipe Lokole's database(s) clean?
(Ideally with Lokole's out-of-the-box settings wiped completely clean, or some such / similar!)

@holta The configuration values are persisted in a file at {{ lokole_run_directory }}/webapp_secrets.sh during the configure step, so to update the values I'd assume that this step has to be re-run (or the file changed manually).

This is the code that creates the config file: https://github.com/ascoderu/iiab/blob/382fa66570f57be84c47bb7fdde7166d213f4bcd/roles/lokole/tasks/install.yml#L41-L46
