Robin Jarry 074b0a1bd8 view,list: fix crash when viewing incomplete imap messages
With IMAP, due to an unidentified reason, some messages to not have any
body accessible. When viewing them, aerc crashes:

  git.sr.ht/~sircmpwn/aerc/lib.usePGP

  main.main.func2
          aerc.go:160
  aerc crashed: runtime error: invalid memory address or nil pointer
  dereference

Check the pointer before dereferencing.

Also, add a global check in ParseMessageFormat where a similar issue may
occur.
