solidity-coverage fixed to version 0.7.2

[elenadimitrova]

solidity-coverage is pinned to specific version, currently 0.7.2. However the latest version is 0.7.4 which includes some fixes for the support of Solidity 0.6. There are likely to be more upcoming minor fixes and I can't see a reason to not allow it to upgrade with something like "solidity-coverage": "^0.7.2"

Currently with the upgraded repo for argent-contracts we get the following error which might be fixed in 0.7.4

Error: Error: Could not instrument: modules/GuardianManager.sol. (Please verify solc can compile this file without errors.) Unrecognized expression
