Fix Numpy deprecation warning in matutils.corpus2dense

[PeteBleackley]

Fix for issue #2432. This is a one line change (generator to list comprehension)

Thanks @PeteBleackley . That doesn't look like a 1-line change though, and there are conflicts.

Can you rebase your changes on top of current develop branch?

[PeteBleackley]

@piskvorky It should be a one line change. For some reason git has included all the commits from my previous 2 PRs (it lives up to its name). I had tried to make sure that I was synced to the latest version of the develop branch before making my changes as well. I'll have to try again.

You could also start from gensim's develop directly, by doing a hard reset: git reset --hard gensim/develop. And after that, re-apply your one-liner.

That way, there's no risk your "local" develop branch already diverged from upstream develop.

@PeteBleackley Are you able to rebase?

This has already been fixed as part of #2371
