[BUG] SecurityViolation when using a project name already used by someone else in same group

In summary:

1. if an import wants to use a project name that other user already is using, the new project is created, the new dataset is created, but we try to link the new dataset to the previously-existing project, which can cause a SecurityViolation.

The bigger issue is that, even though all the data is moved to the correct place server-side (so, for the user, these imports "happened"), the SecurityViolation causes the import to stop.

Possible solution: check Project ownership and create new one if it is not owned by relevant user

[erickmartins]

new cli-transfer based import process will make this moot - user on spreadsheet will be enforced and a new project/dataset will be created for that user even if a different user in the same group has same names.
