Description

When using a wrong call in the template given to the generic method, for example, a call to print a key which has subkeys,
cf-engine will fails to render the template BUT it will use the last template rendering value instead...

The generic method should initialize the content of the rendered template, try to expand it via cf-engine, and then check that
it has successfully been changed before writing it to the result file.

Minimal problem showcase is found below:

bundle agent main {
  vars:
    "test" data => '{"key1": "value1" }';
  methods:
    "any1" usebundle => template("/tmp/test1", "content");
    # Exists bot not displayable
    # The value is not recomputed
    "any2" usebundle => template("/tmp/test2", "{{{vars.main}}}");
}

bundle agent template(dest, template) {
  vars:
    "content" string => string_mustache("${template}", datastate());

  reports:
    "${dest}:${content}";
}`
