Given:
import.data.decision-instance.maxPageSize is configured to 2000

When:
decision import pages are fetched

Then:
the page size is 10000

Expected:
the page size is 2000 as configured by import.data.decision-instance.maxPageSize

Notes:
The DecisionInstanceFetcher uses #getEngineImportProcessInstanceMaxPageSize but should use #getEngineImportDecisionInstanceMaxPageSize.
