### Issue description

When running `!plugin config <plugin-name>`, you get a help message:
>Default configuration for this plugin (you can copy and paste this directly as a command):

When configuring a plugin through chat (Slack backend), there can't be a line break after `!plugin config <plugin-name>`. This means that, because it contains a line break, you cannot copy and paste the default configuration template as the message suggests. If you put the configuration dict on the same line, all works fine; if you put the config on new line, you get:
>Unknown plugin or the plugin could not load \<plugin-name\>.

### Steps to reproduce

Configure a plugin from chat using the Slack backend (I'm not sure if applies to all backends), making sure to include a line break between the plugin name and config dict, like:

```
!plugin config foobar
{...}
```

You will get an error: `Unknown plugin or the plugin could not load <plugin-name>`.

Now remove the line break and try configuring again:

```
!plugin config foobar {...}
```

The configuration will succeed.
