Fix Tutorial: Debugging a Smart Contract

[fainashalts]

This tutorial requires some updates to work properly. This issue arose from work on trufflesuite/issue-target-tmp#1.

Issues to Fix

• need to update solidity version; going past 0.5.0 will require that the get() function in Store.sol is designated as view rather than constant
• typo: “We will see how the issues present itself”
• Running truffle develop —log doesn’t seem to work as expected; perhaps this is a bug? I get a stack trace in the original debugger window. Not sure if that is intentional, but nothing seems to come up within the "log window"
• Getting “transaction completed successfully” in the debug console when there should be something about the while(true) line? And then “Transaction has halted: cannot advance”
• Not seeing a way to get the transaction id for the failed transaction since logging seems not to work?

• main issues seem to be 1) versioning and 2) getting transaction hashes properly for failed transactions (is there a bug or a step missing in the tutorial?)
