Further changes are needed.

- The new dest_dir argument is not passed down to the internal functions, so I 
don’t understand how this is supposed to work.

- install_local_project needs a dest_dir argument too; Jonathan Fernandes 
started work on this at the last sprint.

- The test needs to be improved to really install a module and a script for 
example; I started to do that and also removed the usage of dist.Distribution 
(which is not the kind of distribution the install module works with: it uses 
database.Distribution and pypi.Dist (forgot the exact name) objects — yes, this 
is confusing as hell) but then the test code did not install anything; I ran 
out of time.  I think tests should avoid using dist.Distribution and MagicMock 
but stay as close to possible as real usage:
 - to test installing from a directory, create a temp dir with a setup.cfg 
file, a module and a script and call install_local_project (and other public 
functions that support a dir) with this dir as argument
 - to test installing from an archive, create files, archive them and call the 
public install function with the path to that file as argument
 - to test install_from_infos, call install_from_infos with a pypi.Something 
object pointing to an archive in a temp dir

That way, we could have confidence that all of this works, without explicitly 
using the internal functions in our tests.
