Nunjucks Incompatibility runtime.fromIterator Error

[NatEvatt]

Recently I have been getting the error TypeError: runtime.fromIterator is not a function whenever I try using a precompiled template with a for statement. I figured out that the issue is related to nunjucks version as described in this post on the nunjucks github page mozilla/nunjucks#1091

I have been able to fix the issue by forcing npm to install nunjucks 3.0.x as described in the url above. It would be awesome if gulp-nunjucks were updated to the current 3.1.x.

Thanks
