[Fix]: Allow importing assemblies into exsiting projects and handling the collision (#7108)

* fix: saving off code

* fix: saving off progress

* chore: implemented kcl sample assembly unique sub dir creation

* fix: removing testing console logs

* fix: cleaning up old comment

* fix: add to file always does subdir/main.kcl now for single files

* fix: auto fmt

* fix: delete project and folder from ttc

* fix: fixed deleting projects and subdirs

* fix: if statement logic fixed for deleting project or subdir

* fix: TTC isProjectNew makes main.kcl not a subdir.

* fix: fixing e2e test

* fix: this should pass now
