Bot with long login/nick will get problem with inputparser

What steps will reproduce the problem?
1. We construct a bot with long login/nick
2. The server (mine now is undernet) will accept the connection but return a 
shorter hostmask (passed to inputparser)
3. Input parser will not be able to find the Pircbotx with specified login/nick 
returned by the server.

What is the expected output? What do you see instead?
I think when the server pass back the new login information, the bot should be 
able to pick up the changes and update nick/login information accordingly

What version of the product are you using? On what operating system?
2.0.1 and 2.1

Please provide any additional information below.
Nick: testwithalongnick
Login:testwithalonglogin
