NullReferenceException in Paket.SemVer.Parse(String version)

[mexx]

I was converting a project from NuGet and run into this:

Ausnahmefehler: System.NullReferenceException: Der Objektverweis wurde nicht auf
 eine Objektinstanz festgelegt.
   bei Paket.SemVer.Parse(String version)

Unfortunately I can't share the original project for reproduction.

Paket version: 1.14.0.0

[mexx]

Introduced in 4c1ae17, paket.targets don't have a VersionInfo attached.

paket auto-restore on fails when paket.targets is present.

can you please try to fix it!? thx

ok this makes me think of what do we do with the targets.file.
We can't decide if it's outdated. So let's do a different approach and download all files if one is oudated.
