SetupFinal: Do not display seedwords with comma

[cstenglein]

Response from blitz api:

This is also shown in the webui:

Should be cleaned from commas

[cstenglein]

@rootzoll should I add an issue in the raspiblitz repo so you remove it or should I remove it in the webUI?

[rootzoll]

If you can remove the comma on the WebUI side that would be best.
