Branch clean up deletes plan branch even if VCS branch was deleted and recreated

SUMMARY

Bamboo deletes plan branches after expiry period if a VCS branch had been deleted, even if that VCS branch had been recreated afterwards.

SCENARIO

• VCS branch created in repository, e.g. "B1"
• Bamboo detects the branch and creates a plan branch for it
• VCS branch "B1" deleted from repository
• Bamboo detects the deletion of "B1", disables plan branch and schedules it's deletion
• VCS branch "B1" recreated in repository
• Bamboo ignores it and deletes the plan branch after expiry period (e.g. 7 days)
• Bamboo will never re-create plan branch for "B1" automatically

WORKAROUND

• use different branch name
• (available after BAM-16505) after the plan branch is deleted (after expiry period), manually re-create it in Bamboo

FIX SUGGESTION

Detect that a VCS branch had been recreated and react, e.g.:

• re-enable plan branch & no longer schedule it for deletion, or
• create a new plan branch for it, keeping the old one still in queue for deletion
