HaFlow Create or Update: updateFlowMonitoring throws IllegalArgumentException
Steps to reproduce using the standard test topology:
- create an HA flow with a valid request parameters. For example, use the request below.

Expected result: HA flow is created, no errors in the log
Actual result: there is an error in the logs, however the flow was created successfully.

The same behavior happens when performing an update (PUT). You can use the same request below.


The error:
```
java.lang.IllegalArgumentException: HA-flow ha-flow-1 has no HA-sub flow ha-flow-1-a
```
with the stack trace that includes:
```json
{
  "file": "HaFlow.java",
  "method": "getHaSubFlowOrThrowException",
  "line": 374,
  "exact": false,
  "location": "stormjar.jar",
