RyanVM pointed out the create-a-bug links depend on `JavaStackTrace` and if the crash report doesn't have one, then it doesn't add the stack to the bug. For example: https://crash-stats.mozilla.org/report/index/c2d6398c-284c-4a2b-9dd9-31a3a0240306

In bug #1847429, we sort of fixed signature generation to use `JavaException` when `JavaStackTrace` wasn't available. RyanVM pointed out the create-a-bug links depend on `JavaStackTrace` and if the crash report doesn't have one, then it doesn't add the stack to the bug. Need to look into other places that depend on `JavaStackTrace`. For example: https://crash-stats.mozilla.org/report/index/c2d6398c-284c-4a2b-9dd9-31a3a0240306
