[spotbugs] Fix potential NPE in OpenSshServerKeyDatabase

If oldLine is null #updateModifiedServerKey shouldn't be called since it
would derefence it. Spotbugs raised this as problem
RCN_REDUNDANT_NULLCHECK_WOULD_HAVE_BEEN_A_NPE. Fix it by checking if
oldLine is null before calling #updateModifiedServerKey.
