Brief summary of the bug. What is it ? Where is it ?

Currently in the RawProcessDataResultDtoMapper whenever we calculate flownode durations we always assume that the durations are integers and not longs

Steps to reproduce:

Create a raw data report for process instances whose flownodes have bug durations such that the number is a long

Actual result:

The raw data report crushes

Expected result:

The raw data report should be calculating the durations and display them in the raw data report
