Allow paths from base of repository in `requires`

[maurits-tellow]

Take the following controllers for example:

• src/app/controllers/foo.controller.ts
• src/app/controllers/my-group/bar.controller.ts

And we want to add the requirement for an e2e test file: src/test/e2e/{{name}}.ts

requires: ['../../test/e2e/{{name}}.ts'], then only works for foo.controller.ts.

Add support for: requires: ['src/test/e2e/{{name}}.ts'], and only resolve ./ and ../ from the files own directory.
