Webtop does not restore environment variables from backup

[stephdl]

Steps to reproduce

• Perform a backup of an ns8-webtop module instance.
• Attempt to restore the module from the backup, replacing the existing one.

Expected behavior

• The environment variables from the backup should be restored as they were at the time of backup.

Actual behavior

• The restoration process completes without any errors.
• The environment variables are not restored from the backup; instead, the module ends up with the default environment variables as created by the create-module action.
• Example of default environment variables after restore:
