Subject: Target analysis: report short names of targets when describing a
 conflict

Configured targets, by design, cannot distinguish between a value
not occuring in the configuration and occuring there with value
null. Therefore, to understand the conflict, we can as well drop
all the null values of the target configuration when reporting it.
