Maestro++ has a PR in cache for the repo that was removed or renamed

[andriipatsula]

We have a spike in exceptions in Maestro++ which started about a week ago: Go to Log Analytics and run query.

Maestro++ tries to synchronize a PR in a repo that was removed or renamed (in dnceng/internal project)
PR: https://dev.azure.com/dnceng/7ea9116e-9fac-403d-b258-b31fcf1bb293/_apis/git/repositories/2f49f4d0-c02f-4261-85ee-7186a9e61acc/pullRequests/26594

Most probably that the repository had an open dependency update PR and was removed, and the PR is still in the cache.
The Git repository with name or identifier 2f49f4d0-c02f-4261-85ee-7186a9e61acc does not exist or you do not have permissions for the operation you are attempting.
