Remove logic for multiple error recovery attempts (facebook#23227)

This deletes some internal behavior that was only used by
useOpaqueIdentifier, as an implementation detail: if an update is
scheduled during the render phase, and something threw an error, we
would try rendering again, either until there were no more errors or
until there were no more render phase updates. This was not a publicly
defined behavior — regular render phase updates are accompanied by
a warning.

Because useOpaqueIdentifier has been replaced by useId, and does not
rely on this implementation detail, we can delete this code.
