Nuspec in top directory only (hvanbakel#125)

* Fix nuspec reader to not pick up from obj folder

* Don't lose memory of nuspec file location during transform

* Only look in top directory for nuspec file

* Revert redundant check for obj folder in nuspec reader

We only look in top project directory now, so there is no chance of obj coming into play
