Problem:
When creating a report with a stacked bar visualization and then removing the secondary groupBy so that there are no more stacked bars, goal lines do not work anymore.

Reproduce:

• Create a bar chart report that can have stacked bars, e.g. process instance count, grouped by start date and variable
• Enable Stacked Bars
• Remove the secondary group by
• Add a goal line

Expected:

• Goal line is visible
• chart y axis is adjusted so that the goal line is visible

Observed:

• Goal line is not visible
• Bars that do not reach (or exceed) the goal are still colored in red
• chart y axis only considers datapoints and ignores value of goal
