Subject: [PATCH] add error logs for nil moduleRegistry

Summary:
Changelog: [Internal]

for the last 6 months or so, we've been getting this task where the moduleRegistry in RCTDeviceInfo is nil. in this change, i add some logs to see what might be setting this to nil.

 in all honestly, i don't really think this is happening, but it would be good to verify.
