Solidity-coverage missing dependencies with web3 1.0.0-beta.51

[Andreadinenno]

This issue is a remainder to check updates of solidity-coverage, since in its last implementation it is using web3 beta.50.

This is needed because of an issue of web3, that causes roughly half of our test to fail when run under the solidity-coverage environment, while passing using the latest Truffle/Ganache.

This is currently blocking #97

[zoenolan]

A beta version of solidity-coverage with support for Solidity 0.5.x but is currently untested

[zoenolan]

and after testing the latest beta version that is still producing the error.

New release of sol-coverage, not a simple drop in upgrade

[zoenolan]

v0.6.4 released a while back

[Andreadinenno]

Updated to the latest version of solidity-coverage yet same errors when running the coverage.
Steps to reproduce:

• remove node modules with rm -rf node_modules
• update solidity-coverage in package.json to version 0.6.4
• fresh install dependencies npm install
• run test coverage tool npm run coverage

Error encountered:
TypeError: Overriding function changes state mutability from "view" to "nonpayable" for a bunch of function implementing the IERC777
