[DRE-maint] Bug#952026: fixed in node-handlebars

[Pirate Praveen]

Control: reassign -1 node-handlebars
Control: affects -1 ruby-handlebars-assets
Control: found -1 3:4.7.6-2

Hi Daniel,

Thanks for this information. It gave me an idea to diff between the two 
files and I found the embedded handlebars files were using 'this' and 
our builds were using 'window'.

Looking around I found  webpack option to pass globalObject: 'this' to 
match this format. This option allows the code to run same code on both 
node and browser.

Fixed node-handlebars and will upload now.
