[daisy] daisywiki prefix configuration out of DAISY_HOME

The approach you describe would start two daisy-wiki webapp instances
with the same configuration (using the same wikidata directory, the same
daisy.xconf file and hence the same clientId to connect to the JMS -
that is where the error comes from).

Perhaps you are trying to achieve something which is better solved using
other techniques.  Do you really need to run two daisy-wiki instances on
one machine or do you just want to make sure people do not hit 404
pages?  In the latter case consider a setup where people's browsers
redirected.

HTH,
Karel
