Remove dead uploadstart emitter startUpload()

The loadstart even is only triggered once to indicate the progress has
begun (initialize the progress bar). Essentially, this is dead code for
two reasons:

1. It never gets emitted because initProgressBar() gets emitted first.
2. No JavaScript file in pomf core uses the non-standard uploadstart
event.
