Allow ExCS admin to set starter project identifier

To achieve this, I've had to remove the explicit *overriding* of
`Project#identifier` in `Project::Create.build_project` when the user is
an Experience CS admin.

Note that the `Project#check_unique_not_null` check which is triggered
on a `before_validation` callback will generate an identifier if none is
set in `Project::Create.build_project`
