given:

• I have a group by startDate report and 1000 process instances distributed over more than 1000 days

when:

• I group by days

then:

• I get less than 1000 day buckets in the result

expected:

• I get exactly 1000 day buckets in the result

Context:
When there is no user defined startDateFilter we create a default filter windows from the latest entry - 1000 (groupByUnit). However we do not apply the extendedBounds to ensure potentially leading empty buckets are present in the result.
