Backporting LPS-99857 to 7.0.x revealed an issue where (harmless) freemarker errors are thrown: https://test-1-7.liferay.com/job/test-portal-acceptance-pullrequest-batch(7.0.x)/AXIS_VARIABLE=0,label_exp=!master/27977//consoleText

LPS-99857 created a situation where JournalArticle templates will try to be rendered during an import. If the template needs information from a request, because there is no request during an import or service call, it will fail and throw freemarker errors. The clearest example is when deploying the porygon-theme.war to 7.0.x with the changes from LPS-99857. Because the war imports journal articles with a template which depends on attributes from the non-existent request, a long series of freemarker exceptions appear, one for each article.

Reproduction Steps:

1. Create a new site
2. Goto Web Content and from the upper right ellipsis Export/Import
3. Import Template Export.portlet.lar

Expected Results: The import happens without throwing freemarker errors
Actual Results: Freemarker errors are thrown in logs

[exec] FreeMarker template error. See an example error below. 
     [exec] The following has evaluated to null or missing:

     [exec] ----
     [exec] Tip: It's the step after the last dot that caused this error, not those before it.
     [exec] ----
     [exec] Tip: If the failing expression is known to be legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
