Pass kwargs to object factory - #168

The Issue

When you fetch tags from a project and try to access the builds through a tag commit object like in the following snippet:

client = gitlab.Gitlab(..)
project = client.projects.get('some-id')
tag = project.tags.list()[0]
tag.commit.builds()

… then python-gitlab raises an AttributeError in line 1128 in objects.py. This happens because it tries to construct the request url and cannot find self.project_id.

url = '/projects/%s/repository/commits/%s/builds' % (self.project_id, self.id)

What Causes the Issue?

When you fetch tags python-gitlab constructs Tag-objects which call _set_from_dict internally. Then this method checks if it contains data for subobjects and calls subsequently _get_object . At this point the subobjects will be created from the gitlab response data but do not receive any "kwargs" information and as such are missing the project-id.

Possible Solution

I simply passed down the kwargs to _get_object. It solves the specific issue although I am not exactly sure if this is the best way to go. Additionally I am not a huge fan of passing down parameters for too many levels as it feels conceptually wrong.
