fix(cdk-integ): Update cdk-integ to use new context file (#1962)

Running integ tests is currently broken, since the integ tests will
write context to `cdk.json`, which then gets moved to
`cdk.context.json`. `cdk.json` gets cleaned up afterwards but
`cdk.context.json` does not, so it gets left there and messes up the
next integ run.

Just write all fake context to `cdk.context.json` right now as intended.
