Offload initialization until after initialization completion
Offload initialization until after initialization completion

This change possibly fixes #64 by reordering the initialization phase of
the plugin to load the extension fully only after Xcode sends the
“finish launching” notification. Still unable to reproduce but should in
any case be a good change. ¯\_(ツ)_/¯
