Brief summary of the bug. What is it ? Where is it ?
When creating a set of kpi reports and activating the digest email right I way I hit a nullpointerexception happing due to the complete absence of the previousKpiReportResults (the parameter passed is `null`)
Steps to reproduce:
- Start a new Optimize environment
- Create some kpi reports using e.g. the magic link on the processes page
- Enable the digest email on the process
- Click save
Actual result:
Stacktrace:

Expected result:
- the edge-case of no previous kpi results shouldn't cause a NPE
- actually saving digest settings shouldn't synchronously trigger an email to be sent? ideally this is done asynchronously/different thread to not influence the actual REST call as it actually does in this case
Hint:
It also seems like this is a chicken egg problem due to the error the previous/lastKpiResults never get persisted.
