fix(android): keep layer reference when reordering

[grantsisson]

Description

Fixes #3572 per #3572 (comment). Happy to validate other cases + new arch/v11 if this change seems sufficient. From the discussion seems it should be. Works for my simple bug report.

• I updated the doc/other generated code with running yarn generate in the root folder
• I have tested the new feature on /example app.
  • In V11 mode/ios
  • In New Architecture mode/ios

  • In New Architecture mode/android
• I added/updated a sample - if a new feature was implemented (/example)

Yes we don't have yarn.lock, we should probably have it
