convert: if getting a file from Perforce fails try to get it one more time
When converting a particularly large Perforce changelist (especially with some
big files), it is very likely to run into an intermittent network issue (e.g.
WSAECONNRESET or WSAETIMEDOUT) getting one of the files, which will result in
the entire changelist converting being aborted. Which can be quite unfortunate
since you might have waited hours getting all other files. To mitigate this
let's attempt to get the file one more time, escalating original exception
if that attempt fails.
