Template validation added in pr https://github.com/apigee/apigeelint/pull/383 is incorrect

[edekok-mimecast]

The code dos not seem to work with a JSON template e.g.

<Template>
{
   "field": "{some.value}"
}
</Template>

Change in lib/package/plugins/PO026-assignVariableUsage.js lines 127-130 are causing valid templates to fail

if ( ! pluginUtil.isValidTemplate(templateText)) {
  addMessage(textnode[0].lineNumber, textnode[0].columnNumber,
           "The text of the Template element must be a valid message template");
}

due to lib/package/plugins/_pluginUtil.js: isValidTemplate not expecting { when in STATES.INSIDE_CURLY:
