Elsa 3.3.3. Breaking changes or error within MongoDb Object serialization

## Description
Within Version 3.2.0 it was possible to create variables simply as type object. No matter if the variable contains an array of objects or a single object.
It was possible to store an array of objects within a variable "items" with type object. The "items" can be simply iterated using the "ForEach" activity with the iterator variable "item" with type object. For example:


with ForEach:


My custom delay activity simple "suspends" the workflow and resumes it after the defined time in order to force
a persistation and deserialization of the workflow instance from the MongoDb.

Within version 3.2.0 the test workflow above works without any errors:
I1/N1
I2/N2
I3/N3

Within version 3.3.3 i'am getting serialization error while resuming the workflow:

```
I1/N1
I2/N2

## Steps to Reproduce
Create the workflow above and try to suspend/resume the workflow with your possibilities within the Foreach iteration.

## Expected Behavior
The behaviour from 3.2.0 must be possible in 3.3.3, too. It was very easy, simply define all JSON data as object and never look back, cool.

Or what is the expected way to work with JSON objects and JSON arrays. Type JsonNode, type JSON, JsonElement, ....?

## Environment
- ELSA 3.3.3
- MongoDb persistation

Many thanks for your help!
