onStateChanged not triggering when filters are modified

[tduffield]

Describe the bug
According to the documentation, the onStateChanged callback should trigger when the user adjusts the filtering. However, that does not appear to be happening.
Not sure if the documentation is wrong, or if there is a legit bug in the code.

Steps to reproduce

1. Go to https://surveyjs.io/dashboard/examples/save-dashboard-state-to-local-storage/reactjs#
2. Click on any bar to filter the charts.
3. Click on "Reload this page"
4. See that the filtering has not been saved.

Expected behavior
Based on the documentation, I would expect the filtering information to be preserved.
