[Development branch] Message "Error during inference: null" when introducing impossible evidence

[Manuel Luque]

When the user introduces impossible evidence on an influence diagram in the GUI, in inference mode, OpenMarkov shows the message "Error during inference: null". I would expect something like "Impossible evidence...". I attach a network example: the influence diagram of the decide test problem. This issue can be reproduced by opening the network, clicking on the thunderbolt icon, and then introducing the evidence "Result of test = negative" .

This error is not reproducible (or at least is not failing anymore). But when we introduce a new post-resolution evidence in a variable this are extending the evidence to another variable.
