Run screenshot scroll capture even if type is PROVIDED_IMAGE

Scrolling screenshots don't work in work profile, because we convert
even fullscreen screenshots to "PROVIDED_IMAGE" (and just capture the
app itself) and we don't currently attempt scroll capture for provided
image. This change removes the gate on PROVIDED_IMAGE (since it will
just not run anyway if the task ID is not available) to restore
scrolling functionality to work profile screenshots.
