paket update can't get nuget dependencies with an "." inside the name

Description

In some NuGet package names, we included the version we are currently building to be sure that the project only takes its version dependencies.

nuget net-project-v1-test

In the case we need the create a patch inside this version, the name will contain a period

nuget net-project-v1.1-test

When the main project is doing a paket update to get every package dependencies he needs, Paket update makes an error on the package with "." even if the package is inside the local source.

The error

Please check the feed definition in your paket.dependencies file.

Repro steps

1. Having a project with dependencies that contain a "." inside the package name
2. Build the package with a "." inside the name and copy this package inside a local directory
3. Be sure that the paket.dependencies file have the local directory as a source
4. Before building the project that is inside another directory, make a paket update so paket will get the dependencies
5. Same error should be happening

Expected behavior

paket should be able to get package with a "." inside the name

Known workarounds

Remove the "." inside the package name

Start with Paket.NuGetLocal.getDetailsFromLocalNuGetPackage, identified in the error trace, and reproduce the failure using a local package whose name contains a period. Done means paket update retrieves the package dependencies successfully without requiring the period to be removed.
