Small typo in emacspeak-helm.el

[Lubos Pintes <lubos.pintes@xxxxxxxxxxx>]

Hello,
In emacspeak-helm.el, line 106, there is a typo, the second parameter is 
"emacspea", not "emacspeak" like in other cases.
I quite don't understand the semantics of the second parameter of 
defadvice, so I don't know if it is a problem or not. Jist noticed it.
