[BUGFIX] Do not use fallback temporary directory
[BUGFIX] Do not use fallback temporary directory

With this change you will get an exception if you miss the
temporary path setting in your settings instead of falling
back to the system temporary path, because this could lead to
problems with multiple FLOW3 instances on the same system.

Fixes: #36577
Releases: 1.1
