Fixes a bug in configuring Reservator with scripts. The script-based configuration left the Reservator user email address field empty in the configuration. This email address is given as the only invitee email address when making reservations to the Android calendar. A recent update of Office365 apparently started to require valid email addresses for reservation invitees, and thus the reservations made with script-configured Reservators stopped going through to Office365. This release fixes the user email address field configuration in the script-based configuration.
