order of sources backwards (may be) #233

I'm using the latest paket 0.5.0-alpha005 with this paket.dependencies from SourceLink.

source http://nuget.org/api/v2
source https://ci.appveyor.com/nuget/sourcelink-helmesfwai2a

When I delete the packages folder and run .\paket.exe update, I'm expecting it to try nuget.org and then appveyor.com. Is that the intended behavior? It is acting like F# open statements were the last one wins, but I think it should be the former. Either will work as long as it is documented.

In this case, I end up with SourceLink 0.4.0 locked to appveyor.com instead of nuget.org like I wanted. The workaround obviously being to reverse the order of the sources.
