Brief summary of the bug. What is it ? Where is it ?

When canceling changes on a saved report, some of the configuration that got changed stays until the page is refreshed.

Steps to reproduce:

• Create a new report
• Select View: "Flow Node - count"
• Select group by: "Flow node"
• Select "Chart" visualization
• Save the report
• Edit the report
• change the report view to be "Process instance - count"
• Click "Cancel" to cancel the changes

Actual result:

• The chart report appears on vertical orientation, although the report is saved as a horizontal report. Refreshing the page fixes the issue.
• The axis title show "None" instead of "Flow Node - Count"

Expected result:

• When canceling, the report returns to the exact state when it was saved.

Testing Notes:
Try applying changes (configuration, grouping, etc..) to a saved report and then canceling those changes to go back to the original state.
