largefiles: don't let update leave wrong largefiles in wd if fetch fails

Situations where a largefile for some reason wasn't available sometimes caused
wrong largefile content and state. It has mostly been seen when interrupting
download of largefiles ... and when introducing programming errors.

Instead we now make sure to delete the old and wrong largefile. A missing file
is a well-known error condition and much more reasonable way to handle the
situation.

try:
