Unable to build project after installing npm dependencies without package-lock.json present

[drptbl]

Description: I'm unable to update repository to node 14 and npm 7 because if you remove package-lock.json before installing npm dependencies - you're not able to build the project.

This issue occurs on any node/npm version.

Reproduction steps:

1. git clone https://github.com/Synthetixio/kwenta
2. cd kwenta
3. rm package-lock.json
4. npm install
5. npm run build

I suspect it's a type confict between:

• node_modules/@ethersproject (5.1.0/5.30)
• node_modules/\@synthetixio/contracts-interface/node_modules/\@ethersproject/abstract-provider (5.0.8)

Possibly a breaking change from 5.0.x to 5.1.x+. I've pushed a fix here to bump the ethers version in monorepo packages to 5.3.+
