Context:

With OPT-5515, we have added new fields to the report configuration, specifying the measures visualizations when having multi measure report with bar/line visualization. To ensure the field exists for all previously created reports in ES we should add a migration that adds these defaults to existing reports. 

AT:

• Set the default value for 'measureVisualizations' configuration property to be the following

{frequency: 'bar', duration: 'line'}
