minimap plugin: clear minimap when loading a new track

[othmar52]

maybe related to issue #617

Wavesurfer.js version(s):

wavesurfer.js 6.0.2

Code needed to reproduce the issue:

open https://wavesurfer-js.org/example/minimap/index.html
open js console and add this line

window.wavesurfer.load('https://ia804502.us.archive.org/13/items/DontWatchTheDJ128BPMDry/Don%27t%20Watch%20The%20DJ%20128BPM%20Dry.mp3');

check minimap during load <-- minimap of previous track still visible until load+analyzing is finished

Shouldn't the minimap be cleared automatically when loading a new track?
or is it necessary to destroy() and initPlugin('minimap') manually?

Think so.
