    Fixed incorrect behaviour of method _check_instance_exists

    This method must check instance existence in CURRENT tenant.
    But now it checks instance existence in ANY tenant. It happens
    because parameter project_only=True in sqlalchemy query was missed.
    Also this method must check instance existance in ANY tenant
    if method was called with admin context.

    Due to new behaviour method was renamed to
    _check_instance_exists_in_project

    Tests for _check_instance_exists_in_project were added.
