v0.14.14

RegistrationManagerImpl: catch IOException around refreshPreKeys

Previous attempt wrapped syncRemoteStorage but it's fire-and-forget
(no synchronous throw), so the compiler rejected the catch. The
actual source of the post-registration 403 is refreshPreKeys which
declares throws IOException.

Wrap that one and let registration finish even if pre-key upload
fails in the local dev stack.

Bump to 0.14.14.
