addition of ssh-key for sub-project fails

[gituser]

as the title suggests, steps to reproduce:

1. create a new project project1 without git repository

2. create a sub-project of project1 (lets say project2)

3. try adding a git repository to project2.

the hook won't add the key of the user and sometimes won't create directories for sub-project (i think due project1/project2.git scheme)

happens also in this fork as well: https://github.com/kubitron/redmine_git_hosting/ (latest master revision)

I'm using latest stable redmine 1.3.1 from SVN
