Encode non-ASCII characters in all snapshot tests

Summary:
We're not supposed to commit non-ASCII text to www for some reason. However, some snapshots contained fancy characters.

This diff updates Jest to use the `NonASCIIStringSnapshotSerializer` I added in D16570959 to be used for **all** snapshot tests.
