Cron Header is removed by ghost setup ssl-renew

[yoonsikp]

Issue Summary

Installing on Debian 9.0
Both ghost setup ssl-renew and ghost install with SSL renewal removes the header from the crontab file.

This is the header:

# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)
#
# m h  dom mon dow   command

This header should be preserved for beginner users.

Technical details:

• Ghost Version: Ghost v1.0.0-rc.1
• Node Version: v6.11.1

FWIW - this is not caused by the CLI itself, but by the crontab library the CLI uses to edit the crontab file.

There was the idea of a lineinfile feature for ghost-cli some time back. Alternatively we could switch the crontab lib with one that keeps the comments in the file?

But definitely something after 1.0.0 :-).
