Removing scripts and styles breaks the QueryMonitor plugin.

Hi,

The `SwaggerTemplate::removeQueuedScritps()` method removes all scripts and styles, except `admin-bar` and `dashicons`.

As a result, the output of the [QueryMonitor](https://github.com/johnbillion/query-monitor) plugin is broken. I guess it might also break every plugin that needs to hook into the admin bar and load custom scripts/styles.
