Title:
  Cannot delete build using delete_build

Status in Python Jenkins:
  New

Bug description:
  Requirement already up-to-date: python-jenkins in
  .XXXXXXX/venv/lib/python3.6/site-packages (1.0.2)

  
  In line 357 of __init__.py (function maybe_add_crumb) the code fails on req.headers[self.crumb['crumbRequestField']] = self.crumb['crumb']

  at this point i have a value for self.crumb and req.headers is b''

  the error i get is "bytes' object does not support item assignment"

  trace

   File "XXXXXX.py", line 9, in <module>
      j.delete_build(r"Whale Watchers/Project Whale Watcher QA - Grouped", k)
