fix: ethereumjs-abi ENOLOCAL error

[drptbl]

changes:

• fixed ethereumjs-abi issue on npm install:
  f407fde
• package-lock.json updated after npm install
• switched from npm ci to npm install in CI (npm ci doesn't use cache and npm install is fixed now)

It was already fixed at ganache-core level with same fix (trufflesuite/ganache#653).
However until dependencies which rely on broken ganache-core are not updated to latest with a fix present (which for sure will take some time), this issue will occur. This PR will fix it in synthetix repository and all dependencies which rely on it.
