Stashes based on branches don't show up if the branches got deleted

[cateyes99]

Describe the Bug
Stashes based on branches don't show up in Git Graph, if those branches got deleted.

Steps to Reproduce
Steps to reproduce the behaviour:

1. Create a new branch, make a few commits into this branch (in the example it's called 12204_remove-hardcoded-annualPayment-logic).
2. Make some more changes, and stash them on the new branch.
3. Check Git Graph, you can see the new stash: stash@{0} of b90183c3d4424ccb35af413b1fd8f9d44b4588f2.
4. Delete this new branch.
5. Check Git Graph again, you should be able to see the new stash: stash@{0}. But actually now you don't see stash@{0} now :(

Expected Behaviour
At the Reproduce Step 5, stash@{0} should still display in Git Graph.

Environment

• Git Graph Extension Version: 1.21.0
• Visual Studio Code Version: 1.41.1
• Operating System: Windows 10 Professional

There is another stash@{1} which was stashed based on the master branch quite a while ago. As the master branch is always there, so this stash@{1} still displays itself in Git Graph as shown below.

Thanks for spotting this, I’ll have a fix for this available in the next few days.

This will be available in v1.22.0.

If you'd like to use it before the next release, you can download v1.22.0-beta.4, and install it following the instructions provided here.
