No actions are taken if they are not necessary.

Currently everything brute-force removes everything and re-installs/enables it. That makes the repo slower than it needs to be.
Examples are:

• Setting the GitHub personal access token.
• Setting the GitHub SSH key.
• Removing and pushing the copy of the GitHub repository from GitHub to GitLab for each separate commit, instead preserving the repository in GitLab and pushing the changes per commit.
  ... etc.
