When alignment fails with strict or moderate and relaxes, we call assemble again each time

[joanise]

To reproduce, watch the network requests with F12 in Chrome, load a big text file, record a couple seconds of noise, and then click go to next step.

You'll see in the network traffic that assemble is called again from the backend three times, even though it's getting exactly the same output back each time.

The pipeline should be tweaked to retry only the soundswallower alignment step, with updated parameters each time, not the whole pipeline starting from assemble.

This code is in upload.component.ts, search for retry.
