[Export as JSON] Issues with items that have identifiers stored in configuration

[jvigliotta]

Summary

There is an issue with exporting display layouts (or any item that has configuration that stores identifiers). When we export we find and replace old key strings with new key strings, but this misses the case where identifiers are used (such as above mentioned configuration). This causes odd issues, like display layout items "pancaking" 1:1 coordinates of the grid. This fix adds checks for identifier objects as well and will replace those.

Expected vs Current Behavior

Identifiers should have always been included in the replacement, they are not included in the replacement.

Steps to Reproduce

1. have an linked/aliased item in a display layout that also has a namespace in it's identifier
2. export the item
3. import the item
4. notice that the positions for aliased items are lost

Impact Check List

• Data loss or misrepresented data?
• Regression? Did this used to work or has it always been broken?
• Is there a workaround available?
• Does this impact a critical component?
• Is this just a visual bug with no functional impact?
• Does this block the execution of e2e tests?
• Does this have an impact on Performance?

Will need to test on stable and testathon

@jvigliotta can you provide one for us to import/export?
