Run Placeholder tests in persistent mode, too (#15013)
Browse files Browse the repository at this point in the history 
* Convert ReactSuspensePlaceholder tests to use noop

Instead of the test renderer, since test renderer does not support
running in persistent mode.

* Run Placeholder tests in persistent mode, too

* Fix Flow and lint

* Hidden text instances should have correct host context

Adds a test for a subtle edge case that only occurs in persistent mode.

* createHiddenTextInstance -> cloneHiddenTextInstance

This sidesteps the problem where createHiddenTextInstance needs access
to the host context.
