Patching 1.3 branch with ng build breaking on uglify per 1.5 branch

[jellis]

Whilst I'm aware we probably should be upgrading, we've got a lot of applications that are only being built with 1.3.x - until we're able to get through and test all the breakages, it'd be great if we could get this merged in (as it has been for some other branches/versions).

I've since signed the CLA - the breaking tests appear to be legacy issues (which this branch is likely to be the root cause of).

CLAs look good, thanks!

Hi @jellis, I'm sorry to say but version 1.3 is outside of our LTS and is not kept up to date anymore. The best I can say is that you can use something like https://github.com/ds300/patch-package to change the package in place.

Such is life.
