Expected

As originally reported by #14: type snapshots should update if ESLint is run in --fix mode. For a while they were always being updated (unless disableExpectTypeSnapshotFix was enabled).

Actual

As of #113, type snapshots are only updated if process.argv.includes('--fix'). That doesn't account for programmatic usage of ESLint's Node.js API such as from an editor extension.
