Title: Change "Downloading/unpacking" to "Collecting"

"Downloading/unpacking" was misleading and confusing, especially when the package is never found, as nothing was ever downloaded or unpacked in this case.

The word "collecting" seems general enough to be accurate and it goes well with the fact that later on pip will say, "Installing collected packages".

Fixes: GH-376
