Using fixed 2.2.1 ganache-core version

[macor161]

Fixes #274

This is a temporary fix until we get to know exactly what in the new ganache-core version is causing the bug.

I think we can close this in favor of aragon/aragen#25 which will rebuild the snapshot using 2.3.1, therefore new users will have the correct dependency, and old users can do:
npm i -g @aragon/cli
aragon devchain --reset

thoughts @sohkai ?

@0x6431346e Actually we were debating about publishing a hotfix version with this merged, since 2.3.1 may have snapshot issues and we were having a difficult time generating it through the CI.

Looks like bingen published 5.2.1 with the pinned version 🎉.
Closing for #280
Thank you @macor161!

Yes, sorry, @macor161 I forgot you had already submitted that PR. But thanks anyway for your help!!

Btw, I opened a PR in ganache-core repo, not sure if that's the best way to fix it, but their tests are passing and our cli is working with it:
trufflesuite/ganache#239

@bingen No problem at all :)
