Admin Dashboard Project Count Inaccurate

Summary

Number of projects displayed in the admin dashboard is not updated and inaccurate when new projects are created via the UI or using the API

Steps to reproduce

Create a new project/s and check the admin dashboard project count which will not take into account the newly created project/s

What is the current bug behavior?

Project count is inaccurate in the admin dashboard after new projects are created due to caching.

What is the expected correct behavior?

Project count should accurately reflect the number of projects on the GitLab instance

Possible fixes

Use Project.count to fetch the number of projects in the admin dashboard view instead of using Project.cached_count.
