Data Export does not work when objects selected are in a container's other tabs

When trying to export data from a different tab in container object the data exported will be the one in the first tab (or empty), not the selected data.

Example on symptom:

1. Try to export data to excel from the first table in a container in an app (first object).
2. Open the data and see the data.
3. Try to export data to excel from the second pivot table in the same container and app (second object).
4. See the data is from the first pivot table (first object), instead of second pivot table which was selected.

Export to Excel after switching tab doesn't export the right data
Jira issue ID: QB-1077
Description: Change tab on a container doesn't change the cell that is active on the container. This causes that when data is exported to Excel from the new tab, it is exported the data of the tab that was first active when the sheet was loaded.
