"<Promise> has no method 'finally'" in CasperCG 2.0.7

[JonFranklin301]

Hi There,

I am using CasparCG 2.0.7 and transitioning templates from flash to HTML. I have found that WebCG v2.6.0 does not work with CasparCG 2.0.7

The PLAY command runs but crashes with the error: "Uncaught TypeError: Object #<Promise> has no method 'finally'"

I believe this is as Promise.prototype.finally() has a minimum version of Chrome 63 however CCG 2.0.7 uses Chromium 33. Reverting to WebCG v2.5.0 resolves this issue and WebCG works as expected.

CasparCG log:

Thanks for this really useful library,
