Error after deleting CEL module

Since CEL requires Asterisk 12 or greater, I delete the CEL module if Asterisk 11 is being used.

The following installation script fragment:

if [ "${VER_ASTERISK}" = "11" ]; then
fwconsole ma delete cel
fi
fwconsole reload
fwconsole chown

produces the following error:

Module cel successfully deleted
