Smart Contract Not Compatible with IBM Blockchain Platform 2.5 using Fabric 2.x Images

[celder628]

Fabric runtimes that use Fabric 2.x images have Node version 12 instead of Node version 8 which is used in Fabric 1.4.x runtimes.

The smart contract fabric-contract-api & fabric-shim node modules must be at v1.4.5 or greater to work with Fabric 2.x images.

This is from the smart contract package.json:

"dependencies": {
    "fabric-contract-api": "^1.4.4",
    "fabric-shim": "^1.4.4"
},

This should be updated to:

"dependencies": {
    "fabric-contract-api": "^1.4.5",
    "fabric-shim": "^1.4.5"
},
