Update visualization table after renaming conditions

[dweindl]

Visualization after renaming condition IDs in the condition table fails due to invalid condition IDs. I guess, if a condition is renamed, not only the measurement table should be updated, but also the visualization table.
Potentially the something_changed signal needs to be deferred until after all those modifications then.

Related to #187, Follow-up to #189.

(model1_data3 was the conditionId that was modified in the condition table)

The petab visualization functions should only be called after successful validation, or the those errors need to be caught.
