S3 bucket is not reused with slim_handler: True

[simsong]

When Zappa is using the slim_handler, it does not reuse the temporary S3 bucket that it creates --- Even when zappa update command is used. This results in the creation of many, many, many temporary buckets, until the quota is reached.

Context

This is similar to #1643, except that user is encountering problems with temporary buckets are not needed for the Zappa operation.

Expected Behavior

The created bucket should be reused. Right now, the name is not resused.

Actual Behavior

New buckets keep getting created.

Possible Fix

After a bucket is created, update that zappa_settings.json file to note the bucket name.
