Throw NotConnectedException on login()

Browse source 
if connect() was not previously called. Previously calling login() with
arguments would not check for the preconditions.

The check to throw needs to be performed in AbstractXMPPConnection
before every 'abstract login(Non)Anonymously()' call. That's the two
lines that check the preconditions are duplicated.

Also fix NPE in
XMPPTCPConnection.throwNotConnectedExceptionIfAppropriate() when
packetWrite is null (i.e. if the connection was never connected before).
