login: handle non-tty scenario consistently
Running `docker login` in a non-interactive environment sometimes errors
out if no username/pwd is provided. This handling is somewhat
inconsistent – this commit addresses that.

Before:
| `--username` | `--password` | Result                                                             |
|:------------:|:------------:| ------------------------------------------------------------------ |
|            |            |                                                                  |
|            |            | `Error: Cannot perform an interactive login from a non TTY device` |
|            |            | `Error: Cannot perform an interactive login from a non TTY device` |
|            |            | hangs                                                              |

After:
| `--username` | `--password` | Result                                                             |
|:------------:|:------------:| ------------------------------------------------------------------ |
|            |            |                                                                  |
|            |            | `Error: Cannot perform an interactive login from a non TTY device` |
|            |            | `Error: Cannot perform an interactive login from a non TTY device` |
|            |            | `Error: Cannot perform an interactive login from a non TTY device` |

It's worth calling out a separate scenario – if there are previous,
valid credentials, then running `docker login` with no username or
password provided will use the previously stored credentials, and not
error out.

```console
cat ~/.docker/config.json
{
        "auths": {
                "https://index.docker.io/v1/": {
                        "auth": "xxxxxxxxxxx"
                }
        }
}
⭑ docker login 0>/dev/null
Authenticating with existing credentials...

Login Succeeded
```

This commit also applies the same non-interactive handling logic to the
new web-based login flow, which means that now, if there are no prior
credentials stored and a user runs `docker login`, instead of initiating
the new web-based login flow, an error is returned.
