cdep: use ListContext instead of List to prevent/control context timeout

[inancuvva]

This issue has been faced at two occasions. The issue still present so this piece of tweak solves it by increasing the context timeout and obviously controlling it ourselves within our code. The previous fix was directly in the third party repository however when looking at the List function closely it proxies the call to ListContext function by attaching a content with timeout. We are now calling ListContext with our context.
