Working request with Axios v1.0.0-alpha.1: 
```
axios.get('https://git.somegit.com/api/v3/search/commits?q=sort:committer-date-desc merge:false repo:org/reponame&per_page=50&page=1
```

Same request with 1.0.0 fails with a 404. 1.0.0 was promoted today. 

When I print the failed response it looks like something is parsed/encoded incorrectly. 

```
   request: <ref *1> ClientRequest {
      _events: [Object: null prototype],
      _eventsCount: 7,
       .....
       ..... 
      _headerSent: true,
      socket: [TLSSocket],
      _header: 'GET /api/v3/search/commitsq=sort%3Acommitter-date-desc+merge%3Afalse+repo%3Aorg%2Freponame&per_page=50&page=1 HTTP/1.1\r\n' +
        'Accept: application/vnd.github.cloak-preview+json;application/vnd.github.v3+json\r\n' +
        'User-Agent: axios/1.0.0\r\n' +
        'Accept-Encoding: gzip, deflate, br\r\n' +
        'Host: git.somegit.com\r\n' +
        'Connection: close\r\n' +
        '\r\n',

```
To me the `?` is missing in between `commits` and `q`. 

When I don't parse the parameters on the URL and use `config.params` it works with Axios `1.0.0`. 

```
    config.params = {
        q: `sort:committer-date-desc merge:false repo:org/reponame`,
        per_page: 50,
        page: 1
    }
```

The success response then shows this `_header`: 
```
 _header: 'GET /api/v3/search/commits?q=sort:committer-date-desc+merge:false+repo:org%2Freponame&per_page=50&page=1 HTTP/1.1\r\n' +
      'Accept: application/vnd.github.cloak-preview+json;application/vnd.github.v3+json\r\n' +
      'User-Agent: axios/1.0.0\r\n' +
      'Accept-Encoding: gzip, deflate, br\r\n' +
      'Host: git.somegit.com\r\n' +
      'Connection: close\r\n' +
      '\r\n',

```
In the working version I do see the `?`. 

So right now the workaround is either sticking with v1.0.0-alpha.1 or using config.params instead of passing them with the .get call.
