Specifying prereleases does not work with pessimistic version constraint

[agross]

depfile:

nuget Shizzle ~> 1.0 alpha

There are no released packages yet (i.e. non-prerelease).

± ./paket.sh install
Paket version 2.22.5.0
Resolving packages for group Main:
Paket failed with:
        There was a version conflict during package resolution.
  Resolved packages:
  Could not resolve package Shizzle :
   - Dependencies file requested: >= 1.0 < 2.0
   - Available versions:
     - 1.0.0-alpha002
     - 1.0.0-alpha001

  Please try to relax some conditions.

It works when this is in the depfile:

nuget Shizzle >= 1.0 alpha
