Automatically add a new line at the end of wfLogDBError()

Automatically add a new line at the end of wfLogDBError()

I found two calls to wfLogDBError() that do not add a new line
at the end of the message. So instead of adding them to that
entries, I changed wfLogDBError() to automatically put it on
icoming messages; as for wfDebugLog().
