[Bug 1812148] Re: openstack-dashboard failed to upgrade with custom theme

[Seyeong Kim]

This issue is happening because there is no 'default' theme in
AVAILABLE_THEME

when custom theme imports default theme's file(scss)

I uploaded patch for this in case someone want to import default theme
rather than creating whole theme seperatly.

  Removing the custom themeing bits from /etc/openstack-
  dashbaord/local_settings.py allowed the upgrade to complete but of
  course, this customer does not have a custom theme any more.
