[Console] Fix an error with folds in the editor (#152366)

## Summary
Fixes #151563 

There is a combination of the folds in the editor (collapsed lines) and
the text that can cause the editor to fail. This PR adds a try/catch
clause to the editor, so that the UI can still be used.


### How to use
1. Open Kibana and in your browser's Dev Tools, delete everything from
local storage.
2. Add following 2 items back to the local storage: 
```
sense:folds	[{"start":{"row":1,"column":1},"end":{"row":82,"column":4}}]
sense:console_local_text-object_e69f508c-3342-45cf-ae7c-2753548ce8e7	{"id":"e69f508c-3342-45cf-ae7c-2753548ce8e7","createdAt":1675332935410,"updatedAt":1676630754720,"text":"GET _cat/indices"} 
```
3. Navigate to Console in Kibana, make sure the editor works.
