Incorrect casing in the clone url owner causes issues

[StanleyGoldman]

Issue

If you clone a repo using incorrect casing in the owner. Some functionalities just don't work.

• Visual Studio is https://github.com/github/VisualStudio.git
• If you instead clone it with https://github.com/GitHub/VisualStudio.git

The following functionalities are broken

• Any checked out branch will not be correlated to the corresponding pull request.
  

  VisualStudio/src/GitHub.App/Services/PullRequestService.cs

  Line 527 in 4af9d1c

  return pullRequest.HeadRepositoryOwner == repository.CloneUrl.Owner;

• Checking out an internal pull request will result in the branch path resembling that of a fork pull request checkout
  

  VisualStudio/src/GitHub.App/Services/PullRequestService.cs

  Line 395 in 4af9d1c

  else if (repository.CloneUrl.Owner == pullRequest.HeadRepositoryOwner)

• Multiple pull request sessions can exist
  

  VisualStudio/src/GitHub.InlineReviews/Services/PullRequestSessionManager.cs

  Line 228 in 4af9d1c

  var key = Tuple.Create(owner, number);

  • The OpenFileInWorkingDirectory functionality does not work.

Other suspicious code paths

• VisualStudio/src/GitHub.VisualStudio.UI/UI/Views/GitHubConnectContent.xaml.cs

  Line 78 in 4af9d1c

  if (context.SectionConnection.Username == item.CloneUrl.Owner)

Original Issue

I noticed this while working with another project...

VisualStudio/src/GitHub.App/Services/PullRequestService.cs

Lines 525 to 528 in 4af9d1c

	public bool IsPullRequestFromRepository(ILocalRepositoryModel repository, PullRequestDetailModel pullRequest)
	{
	return pullRequest.HeadRepositoryOwner == repository.CloneUrl.Owner;
	}

pullRequest.HeadRepositoryOwner is "justaprogrammer"
repository.CloneUrl.Owner is "JustAProgrammer"
