[FIX] project: fix no content helper in project sharing

Steps:
- Install project app.
- Share project editable to user which has no
task.
- Open that project in project sharing.

Issue:
- No content hepler is not properly showing.

Cause:
- Helper in project sharing action is not markup
even and that action is type object so we have to
markup no content manually.

Fix:
- Markup project sharing helper.
