Patch

For instance, the following query in master returns the following stacktrace:

```
$ Tools/Scripts/webkit-patch bug-search creator=dpino@igalia.com
Logging in as dpino@igalia.com...
Traceback (most recent call last):
  File "Tools/Scripts/webkit-patch", line 80, in <module>

    return self._fetch_bugs_from_advanced_query(quicksearch_url)

    result_count_text = BeautifulSoup(results_page).find(attrs={'class': 'bz_result_count'}).string
AttributeError: 'NoneType' object has no attribute 'string'
```

The syntax of query is not valid (the 'creator' field doesn't exist). The same query with the patch applied returns:

```
$ Tools/Scripts/webkit-patch bug-search creator=dpino@igalia.com
Logging in as dpino@igalia.com...
BeautifulSoup returned None while finding class: bz_result_count in:
<response_seek_wrapper at 0x7f5b712bda50 whose wrapped object = <closeable_response at 0x7f5b712df0f0 whose fp = <socket._fileobject object at 0x7f5b712dc1d0>>>

No bugs found matching 'creator=dpino@igalia.com'
```

The correct query would be:

```
$ Tools/Scripts/webkit-patch bug-search reporter=dpino@igalia.com
```

A valid query that returns no results would be:

```
Tools/Scripts/webkit-patch bug-search reporter=xyz@igalia.com
Logging in as dpino@igalia.com...
BeautifulSoup returned None while finding class: bz_result_count in:
