Fix of SPE-753

Slicer crash when SLA printer is selected and printer profile is changed

First, there was a bug in the preset Tabs, where a "printer_technology"
was incorrectly queried on "print" and "filament"
(or "sla_print" and "sla_material") profiles.

Second, there was an unsafe "printer_technology" getter, which would add
the missing key to the config container when queried for.
