Rendered content output to stdout twice

[salotz]

This only happens when the template is coming from a file. For instance this works as intended:

--> HELLO="hello there" moban "Here is my greeting: {{HELLO}}"
Here is my greeting: hello there

But if you are getting it from a file for example template.txt.jj2:

{{HELLO}}

where data.yaml is:

HELLO: "hello there"

These result:

--> moban -c data.yaml -t example.txt.jj2
hello there
hello there

--> HELLO="hello there" moban -t example.txt.jj2
hello there
hello there

I have a fix, just prepping the PR.
