1) Activate installed filament or SLA material profile after update_compatible(),
so that the compatiblity and visibility flags of presets are updated.
2) Only activate the first newly installed filament / SLA material profile
if the active printer did not change. This also means that if no filament
profile was active before Wizard was open or it became incompatible with
the newly installed Printer profile, the default filament profile assigned
to the activated Printer is activated preferably, which may or may not
be one of the newly installed filament profiles.
