Subject: [PATCH] libslic3r: say what the write-back catch in
 commit_user_preset covers

Preset::save throws a runtime_error only when it cannot create the preset's
folder; a failed write is silent, and invalid UTF-8 throws a type_error that
is not caught here. The comment now claims only the case the catch handles.
