Subject: [PATCH] Jest setup: Stop polyfilling Promise.

It looks like this line was introduced in 3ff3987, in 2015, and it
has remained in a similar form since then. I haven't found any
explanation for it.

At facebook/jest#10221 [1], a core Jest maintainer says,

"""
As an aside, one should never replace `global.Promise` [...]. E.g.
when using `async-await` you will always get the native `Promise`
regardless of the value of `global.Promise`.
"""

facebook/jest#10221 is one issue this line has raised, for anyone
using the latest features of Jest to test async code in their React
Native projects.

Fixes: #29303
