filebrowser: Don't change directory on project save

This behavior might be unwanted when changing project settings which
is unrelated to project base path and also fixes filebrowser behavior
with the updated way project-save signal is emitted.

The patch also handles the situation where "realized" is called after
project-save is called and overrides file browser's path (which is
something we don't want).
