Context:

When adding support for native JSON variables we altered the ObjectVariableService in a way that some object variables that do not have the appropriate JSON serialisation are still imported due to an incorrect if/else condition. This needs adjusted to exclude this type of variable from being imported.

This should also resolve the issue with UpgradeEsSchemaIT failing with an incorrect variable count.

AT:

• Optimize does not import non JSON serialized object variables
• This is asserted in IT
• UpgradeEsSchemaIT variable count assertion is reverted to equals rather than gte

For QA: This can be tested by checking that Optimize does not import any object variables that do not have the json serialisation type. The default engine processes come with a variable called "approverGroups" that is an example of this, or alternatively this can be tested with external variable ingestion.
