generate-include-scripts generate wrong path for include

[enricosada]

The path generated in the include script is wrong

as you can see in the appveyor build:

• fails in VS 2017 image (but is same error on travis too with mono 5.2)
• ok in VS 2015 image

i repro'd locally, but cannot atm, dunno what is the exact combination

Repro steps

For now is long, sry

1. clone repo at commit ionide/FsAutoComplete@b089e6a
2. .paket\paket restore

Expected behavior

the file .paket\load\net45\IntegrationTests\Http.fs.fsx contains

#load @"Hopac.fsx" 
#r "../../../../packages/integrationtests/Http.fs/lib/net40/HttpFs.dll" 

Actual behavior

the file .paket\load\net45\IntegrationTests\Http.fs.fsx contains

#load @"../../../../src/FsAutoComplete.Core.VerboseSdkHelper/.paket/load/net45/IntegrationTests/Hopac.fsx" 
#r "../../../../packages/integrationtests/Http.fs/lib/net40/HttpFs.dll"
