Subject: [PATCH 3/9] fix(auth): do not cast exit status if `QProcess` is not
exited normally
A QProcess::CrashExit happen in most cases when a signal killed it. And
returning from a signal-killed process on Linux makes QProcess:finished
return the signal, which is a really bad idea to cast into a random
enum.
Qt also mentions that `exitCode` is only valid for QProcess::NormalExit
invocations

UserSession
This will allow HelperApp to dinstinguish between a crash (most likely

Subject: [PATCH 9/9] fix(helper): disconnect `sessionFinished` when exiting
Calling `UserSession::stop` results in a call to `QProcess::terminate`,
which sends a SIGTERM to the session. `QProcess` will catch that and
emit an excess `QProcess::finished(15, 1)` which we don't want to handle
since we are in the process of exiting.
