@joystream/types: remove need for lib from import path

[mnaamani]

• Finally getting rid of need to have /lib/ in the import path.
• Enabled forceConsistentCasingInFileNames tsconfig option which
  "Disallow inconsistently-cased references to the same file"
  This option would have detected the issue we once had on OSX Pioneer: Fix for #511 #514
• Updated cli and tests in nicaea branch to use new path

[mnaamani]

Doing a test by packing the package with npm pack when I try to install it, it actually runs build script, and I'm getting some errors:

$ npm run build
npm WARN lifecycle The node binary used for scripts is /var/folders/x1/jzcg_82x2yndlklx7ystth580000gn/T/yarn--1593013889109-0.3527586406031573/node but npm is using /usr/local/Cellar/node@12/12.18.0/bin/node itself. Use the `--scripts-prepend-node-path` option to include the path for the node binary npm was executed with.

Found 3 errors.

Will try to resolve

Fixed by adding missing dependencies in 26c008f

[Lezek123]

Seems to work fine after removing node_modules inside the root and project folders and running yarn install.
Tested CLI, Pioneer and Network Tests.
Also tried using the tarball created with npm pack within the CLI.
Didn't run into any issues that I could track to changes introduced in this PR.

Merging this will require updates in: #707 (where some additional imports using the old /lib path were included)

[Lezek123]

I'm not sure why this is inlcuded as part of .gitignore

[mnaamani]

Added it to ignore the role.schema.json which is moved into there because its imported by src/hiring/index.ts

import * as role_schema_json from './schemas/role.schema.json'

I will be more explicit and make it ignore that exact file.

I confused hiring/schemas with src/hiring/schemas, now it makes sense, I think it's good to go then.
