vt71: Report Creation/Editing Regression Bug (Save and Generate Buttons missing)

1. Create a Report with one or more conditions
2. Run your report
3. Export the data, csv or Excel
4. Customise the conditions in the "Modify Conditions" area
5. Run the report using the "Generate Now" to test your new condition

The Save and Generate buttons are now removed so you cannot Save your changes. The only way to get the Save and Generate Now buttons back is to add a new condition in the Modify Conditions area and then remove it again. This brings back the buttons.

This was not an issue in vtiger 6 so this is a regression.
