Fix Salt file.managed state without content replacement

Summary:
Suppress the following warning:

[WARNING ] State for file: /srv/api/data/servers-log-all.json - Neither
'source' nor 'contents' nor 'contents_pillar' nor 'contents_grains'
was defined, yet 'replace' was set to 'True'. As there is no source to
replace the file with, 'replace' has been set to 'False' to avoid reading
the file unnecessarily.

This is a follow-up for 87580901de7f.

Test Plan: salt-call --local state.apply roles/webserver-content/org/nasqueron/api test=True
