Update version to 3.25.3

Just tracking upstream.

Note that with an API 25 and API 26 emulator running, I am not able to run connectedCheck successfully, but this is not new to this PR. It just bears mentioning as I am unsure how to verify the correctness of the work here:

Thanks @npurushe - we support API15+ with about a million users in our open source project and almost all our crashes are native sqlite things that are fixed upstream, so I appreciate the work on requery letting us get the fixes out 🍺
