Make restore command check if dependencies and lock file are in sync #1750

This may be an issue in Paket.VisualStudio in fact so i'll post in both and well see where it goes

Description

Open a project with changes on Paket.dependencies does not impact paket.lock
The Idea should be :
When you get the Latest source control version, open it and rebuild it (the solution).
You should be using the "dependencies" version, even if it means updation paket.lock
(see repro step)

Repro steps

Please provide the steps required to reproduce the problem

1. Create a solution that use paket and where paket.dependencies have something like :
   nuget MyLib 1.0

   paket install

The paket.lock is created, Build your solution and the close Visual Studio
2. To simulation a change on SourceControl open your "paket.dependencies" and change it :
nuget MyLib 2.0

1. Re open your solution in Visual Studio Try to rebuild all ...
   You'll see that "paket.lock" did not took the v2.0 of the lib but is still using 1.0
   But paket.dependencies indicate v2.0

Expected behavior

Please provide a description of the behavior you expect.

Actual behavior

Known workarounds

Force "Install manually" when you open the solution (it's a bit f*** up right ?)
