[dev] Auth bug

[KaalH!]

With HEAD, when login to horde with imp, I sometimes got this error :

Notice: unserialize() failed at offset 0 of 37 bytes in /home/smol/tools/horde-
dev/lib/Auth.php on line 299

I finally found what appends.

When login whith imp, the secret key used to store user info is "imp".
So, in non-imp operation (ex: changing horde options), horde try to retrieve 
secret information with the "auth" key, this is the bug !

a small fix (only if log in with imp):
