Storage: Possible metadata regression on blobs in 1.24.0
#### Environment details

* Debian 10
* google-cloud-storage version: 1.24.1

#### Steps to reproduce

It's documented that metadata that isn't set will return a NoneType. Naturally, when wanting to unset any metadata, you expect to be able to pass in `None`. This worked up until 1.24.0 which broke this with googleapis/google-cloud-python#9796.

I think you can still technically set the metadata to an empty dictionary and get the same functionality, but it's a bit counter intuitive, when no metadata is described as being a `NoneType`.

#### Code example

```python
storage_client = storage.Client(...)
blob = storage_client.get_bucket('abc').get_blob('abc')
blob.metadata = None
blob.patch()
```

#### Stack trace

```
