* test: update tests to work with new stricter tsconfig file inclusions
* fix(@schematics/angular): exclusively list the files in tsconfigs

The baseUrl is used for non relative module imports, and we should always use the baseUrl set in the workspace tsconfig. When having path mappings set at workspace level and setting a `baseUrl` in the server tsconfig, this paths will no longer work as paths mapping as relative to the baseUrl.
