Update dependencies

[filips123]

Update dependencies in yarn.lock. Related to #2070 and resolved sha3 issue. There is still a problem with scrypt because it is used by old Web3 versions.

Coverage remained the same at 70.123% when pulling f700c95 on filips123:update-dependencies into 37e99cc on trufflesuite:develop.

Thanks for this!

Does this also need the package.json files updated? Or do they already account for the new versions?

EDIT: Oh, did you just delete the yarn.lock and regenerate it?

[filips123]

This is probably enough because sha3 is required with ^1.2.2 which will also require 1.2.3.

I didn't delete and regenerate yarn.lock. I just tried to upgrade sha3 to 1.2.3. But it looks like yarn did that 😀

Thanks for this @filips123 !

Verified locally that this is indeed a simple yarn upgrade that upgrades the resolved sha3 dependency to 1.2.3.

Before yarn upgrade: https://travis-ci.com/filips123/truffle/jobs/204732468#L796 (failing on node 12 because of sha3)
After yarn upgrade: https://travis-ci.com/filips123/truffle/jobs/204809466#L737 (failing on node 12 because of scrypt)

I was hesitating about the pros/cons of this approach, since there's potential risk upgrading all the packages en masse, but I second @CruzMolina's approval. The risk is relatively low, and potential problems are likely to be easy to mitigate.

Thanks again @filips123 for helping to address the lack of Node v12 support!
