Description

• When the user is adding a new account from GitHub or GitLab, the configURL parameter for initialize GitHubTokenConfiguration is nil, which will generate error. Added a ?? GitURL.githubBaseURL to fix this issue.
• Use providerLink as a part of account ID and serverURL instead of server.
  • This fixes the problem that the same accounts from GitHub/GitLab can be added multiple times.
  • This fixes the problem that the provider icon for GitHub/GitLab accounts cannot be displayed correctly.
  • This should not influence the GitHub enterprise or GitLab self-hosted accounts because in that case, providerLink is server.
