Match package versions after hoisting

Since we introduced `$ lerna bootstrap --hoist`, we now notice that versions of some third-party dependencies within the packages do not match the versions as defined in root `package.json`.

We need to fix them.

```
lerna WARN EHOIST_ROOT_VERSION The repository root depends on react@^16.0.0, which differs from the more common react@^15.5.4.
lerna WARN EHOIST_PKG_VERSION "frint-react-server" package depends on react@^15.5.4, which differs from the hoisted react@^16.0.0.
lerna WARN EHOIST_ROOT_VERSION The repository root depends on react-dom@^16.0.0, which differs from the more common react-dom@^15.5.4.
lerna WARN EHOIST_PKG_VERSION "frint-react-server" package depends on react-dom@^15.5.4, which differs from the hoisted react-dom@^16.0.0.
lerna WARN EHOIST_PKG_VERSION "frint-cli" package depends on lodash@^4.17.4, which differs from the hoisted lodash@^4.13.1.
lerna WARN EHOIST_PKG_VERSION "frint-router" package depends on lodash@^4.17.4, which differs from the hoisted lodash@^4.13.1.
```

Inspect the root package.json and the package manifests for frint-react-server, frint-cli, and frint-router. Compare their React, react-dom, and lodash versions with the root versions, then run lerna bootstrap --hoist and confirm the listed version warnings are resolved.
