Batch modification needs to handle requests containing values for both fromFlowNodeId and fromFlowNodeInstanceKey

[johanwelgemoed]

Describe the bug

• When we specify a fromFlowNodeId parameter, we read all instance keys for that flow node definition and do a modification for each
• When we specify a fromFlowNodeInstanceKey parameter, we only modify that one flow node
• If the request has values for both fromFlowNodeId and fromFlowNodeInstanceKey, then fromFlowNodeId behaviour takes precedence. It feels to me like it should be the opposite: if you specify fromFlowNodeInstanceKey you will only modify that one even if you also specify fromFlowNodeId

Current behavior

• If the request has values for both fromFlowNodeId and fromFlowNodeInstanceKey, then fromFlowNodeId behaviour takes precedence.

Expected behavior

• if you specify fromFlowNodeInstanceKey you will only modify that one even if you also specify fromFlowNodeId
