mail aliases not added to user objects anymore (with error)

[sunweaver]

Today a customer reported these errors:

May  7 09:13:23 tjener php: GOsa[gabmik]: (view) error : PHP error: count(): Parameter must be an array or an object that implements Countable (/usr/share/gosa/plugins/personal/mailaddress/class_mailAccount.inc, line 277) 
May  7 09:13:23 tjener php: GOsa[gabmik]: (view) error : PHP error: Invalid argument supplied for foreach() (/usr/share/gosa/plugins/personal/mailaddress/class_mailAccount.inc, line 279) 

They were caused by a tiny line of code sneaked in via 9dbea004.

This reverts that line. Please note that maybe not all attributes must be strings, some may be arrays. Maybe all should be arrays (as it was before).

The thing is that _user_properties_extras only contains 1 key in my test case ('alias'). So, maybe for some attributes/keys the array to string conversion might be correct while it certainly is not for the alias attribute (there can be more than one aliases per user object).

@dzatoah Please check!
