Revert "[pm/incremental] start monitoring progress on storage creation"

This reverts commit 31fa0fc9c1.

Reason for revert: Play data loader doesn't write data to incfs during "Downloading...", so we shouldn't use incfs progress to replace install progress. Reverting this, so that Launcher will display the install progress ring during "Downloading..." using the progress reported from Phonesky.
