test: cli init with local typeorm package (#9926)

* test: cli init with local typeorm package

Uses the locally built files instead of the typeorm
package published to npmjs. This enables testing project
initialisation with unreleased typeorm package versions.

* fix: enable init cli to be testable w non-releases
