* Agent Host changes for agents/fix-command-batch-history-restore
* Implement centralized transactional fix for command batch failures - #1
* The batch rollback tests compile, are formatted and expect the tab that was in front
The new module used a private helper of plugins_tests and an unused import; the plugin test
asserted tab 0 was in front, but it opens a second file first, which is the one in front
when the plugin starts and the one the rollback puts back.
