contracts don't work if we use serde_json = "1.0.0"

[janedegtiareva]

Steps to repro: use contract from near/create-near-app#65
use serde_json = "1.0.0"
deploy app and run (yarn start)

when running app, get GasInstrumentation failure (see screenshot)

What node version are you using? If you are using docker image then we don't have floats enabled there yet, which is what needed for using serde_json 1.0.0. This will be fixed in the next version.

Testnet:
{"chain_id":"testnet","rpc_addr":"0.0.0.0:8080","sync_info":{"latest_block_hash":"DRzfUJHw2NjoFF3mZaQieynQ5rtaG3fb43zbFQSpiEyd","latest_block_height":636218,"latest_block_time":"2020-01-27T19:31:35.350132049Z","latest_state_root":"BWFyPZ12pUXZiLvF2CaVmF7hvJC25wNJrbaCkgSKHToU","syncing":false},"validators":[{"account_id":"far","is_slashed":false}],"version":{"build":"1a0ea717-modified","version":"0.4.12"}}

Let's hold off using 1.0.0 in create-near-app until the fix is rolled out everywhere. I want to use create-near-app at the hackathon in order to test drive the experience.
