Productivity Analytics: Reset MR table page on main chart click

What does this MR do?

This is behind the productivity_analytics feature flag.

This MR makes sure that we reset the page for the MR table to 0 when an item on the main chart is clicked. Otherwise we would load the MR table with the previously selected page.

In addition, it this hides the „no data“ message for the MR table while the loading indicator is displayed.
