#553: GetComponents needs to undo "git stash" on errors

     Type:  defect         |      Status:  new  
 Priority:  critical       |   Milestone:       
Component:  GetComponents  |     Version:       
 Keywords:                 |  
---------------------------+------------------------------------------------
 GetComponents stashes local changes to a git repository before trying to
 pull. When there is an error, it needs to undo this (git stash pop).
 Otherwise the user sees the local changes disappear, and needs to run this
 command manually for all repositories where git pull failed.
