      A multibranch job that pulls from mercurial deletes all branches when that repository goes down. This was discovered during Bitbucket's outage going on today, and I lost all the branch build history.

      Steps to reproduce:

      1. Create a local mercurial repo with below basic Jenkinsfile and publish using hg serve
      2. Start vanilla weekly docker image
      3. Install multibranch, mercurial
      4. Create multibranch job pointing at that repo, let it scan and build default branch
      5. Kill hg serve
      6. Run "Scan Multibranch Pipeline Now", all branches get deleted

      Basic jenkinsfile

      pipeline {
          agent any
      	stages {
      		stage("Build Data") {
      			steps {
      				sh 'echo yay'
