use separate functions for importing and resetting default shortcuts
* shortcut-manager.h, shortcut-manager.cc
(shortcut_manager::import_shortcuts): Don't reset defaults if settings
is nullptr. Handle that case in a separate function.
(shortcut_manager::reset_default_shortcuts): New function, adapted
from previous import_shortcuts function.
