vhost remove should check if there is a ssl apache config file

[catlynce]

When removing vhost two files are removed:

• the main apache conf file
• the custom avanti conf file

The problem: if there is a ssl conf file in /etc/apache2/sites-available it will have a reference to the already removed custom avanti conf file and then apache configtest task will return an error.

Solution:
vhost.remove should check if the host as ssl enabled and remove the fle before removing the avanti conf file.
