Reset chart when arriving on page #3033

When checking random data on a chart, then clicking on "Edit in jmp questionnaire",
and then coming back to chart, the chart object, still has filters but they may be async
with those we pass in url, so we have to reset chart on page loading.
Perform better system for navigation between chart and table/filter #3033

Know we have a button to edit NSA in NSA and JMP in JMP. It filters the good
data for each view  to avoid bad questionnaires or filters  to appear in the wrong view.

The system is still not perfect, the actual limitations are the following :

- When you go from chart to table, system consider only first filter set (table is mono filterset)
- When you come back from table, you see on chart only informations that were on table
