Do not abort if we could not get a KeyManagerFactory

using the default algorithm. Instead continue with 'null' as value of
the KeyManager[] array (kms). This makes the SSLContext.init() methods
to search the default security providers for implementations, which is
also OK.

This change is needed because it appears that on Android
KeyManagerFactory.getDefaultAlgorithm returns 'SunX509', which
subsequently results in

W/AbstractXMPPConnection: Connection XMPPTCPConnection[not-authenticated] (0) closed with error

      at java.lang.Thread.run(Thread.java:818)

Note that this is possibly because the Secuurity Provider was
not (yet) intialized.
