HTTPS Automatic Upgrade when disabled.

[OllieSteam]

Describe the bug The following command sudo lxdmosaic.disable-https does not disable HTTPS. I am trying to put my mosaic instance behind an Nginx proxy and need to disable HTTPS as this is managed by the Nginx proxy. Terminal suggests it is disabled but when trying to access the mosaic instance I get ERR_SSL_PROTOCOL_ERROR suggesting apache is still auto-upgrading the connection to HTTPS.

To Reproduce Steps to reproduce the behavior:

1. Change SSL Port and HTTP Port using sudo snap set lxdmosaic ports.http=100 ports.https=543
2. Ensure HTTPS is 'disabled' lxdmosaic.disable-https
3. Access the site.

Expected behavior No auto-upgrading of non-HTTPS connections when disabled.
