Bug#394462: 000-default symlink get's added on upgrade

[Stefan Fritsch <sf@sfritsch.de>]

I upgraded apache:

[REMOVE, NOT USED] libapr0
[INSTALL, DEPENDENCIES] apache2.2-common
[REMOVE, DEPENDENCIES] apache2-common
[UPGRADE] apache2 2.0.55-4.1 -> 2.2.3-3.1
[UPGRADE] apache2-mpm-prefork 2.0.55-4.1 -> 2.2.3-3.1
[UPGRADE] apache2-utils 2.0.55-4.1 -> 2.2.3-3.1
[UPGRADE] libapache2-mod-php4 4:4.4.2-1.1 -> 6:4.4.4-8
[UPGRADE] php4-common 4:4.4.2-1.1 -> 6:4.4.4-8

and the sites-enabled/000-default symlink got added even though it has 
not been there before.
