Problems with more than one feed #814

I'm having problems with one of the latest paket binaries (1.3.8). It seems that 0.4.2 doesn't show those problems.

1. BUG1 and BUG2 may be inappropriate usages of paket or bugs (I'm not sure).
2. WEBAPI fixes the problem (encountered by BUG1 and BUG2) by clearing paket.dependencies file.
3. BUG3 scenario seems to be a bug.
   3a. SANITYCHECK confirms that Newtonsoft.Json is available on the internal feed.

Unfortuantely I am not able to send you a repro because of the internal feed involved.

source https://nuget.org/api/v2 //Created by WEBAPI

nuget Microsoft.AspNet.WebApi //Created by WEBAPI

When:
paket add nuget log4net project PaketSandbox
