Synchronization channels between scoring and analyzer do not update correctly

I detected a problem on the synchronization channels.

For reproduce the bug:

0. Use the toolchain: full_fisherface
1. Remove the two cables between the analyzer and the two scoring blocks.
2. Configure the two scoring block by synchronization channel of development sets (dev_templates and test_templates), before to connect to the analyzer.
3. Connect the outputs of the scoring blocks to the analyzer.
4. Change the synchronization channels of the scoring blocks to dev_probe and test_probe
5. voila!: the synchronization channel of the analyzer does no change (is configured based on the dev_templates and test_templates)

Solution: Disconnect the cables between the two scoring blocks and the analyzer and reconnect, then you can select in the analyzer the synchronization channel of dev_probe or test_probe
