fix: hideHeaderIfNecessary for Fabric

[kkafar]

Description

Added the fix introduced here:

• fix: Adds dispatch for hiding header #1153

for Fabric.

Changes

• Moved hideHeaderIfNecessary method to common section
• Added fix for Fabric: when returning from second screen application would crash due to order of view unmounting (child-first) on Fabric (calling view.reactSubviews[0] would cause application to crash)

Test code and steps to reproduce

• Moved Test1153. See: fix: Adds dispatch for hiding header #1153
