Recreated entity with same name

Summary:
When create new entity with specific name "MyEntity", table will be created as name "myentity" with nothing ticked as options (Created, Changed, Author, Language).
There is an issue when the entity described is deleted and recreated with same name and "Created" option is ticked. The table is not removed and recreated with create field added.

Hence, it will cause error when to add new entity because the field is not consistent with the configuration.

Version History:
Drupal: 8.0.0 beta 9

Steps to reproduce:
1. Download and install the Drupal core
2. Download and install the module manually
3. Create new entity with nothing ticked
4. Remove the entity
5. Add new entity with same name and "Created" ticked
6. Create new entity content
7. Save
