dev_settings: Remove accidentally-pushed OAuth app IDs.
dev_settings: Remove accidentally-pushed OAuth app IDs.

These aren't of much use without the corresponding secrets (despite us
calling one of them a "key", both are public IDs), which are in my
personal dev-secrets.conf.  So, remove them.

I had this commit applied in order to test what became 90944983f...
and then I accidentally included it in what I pushed, as 0fa9a489d.
Oops.
