Which one takes precedence depends on your PATH.

However if it is getting loaded through (a systemd) service then it will 
likely directly execute the old one.

Looking at the filelist

/etc/xdg/autostart/tracker-store.desktop
/usr/lib/x86_64-linux-gnu/tracker-1.0/writeback-modules/libwriteback-taglib.so
/usr/lib/x86_64-linux-gnu/tracker-1.0/writeback-modules/libwriteback-xmp.so
/usr/share/dbus-1/services/org.freedesktop.Tracker1.Writeback.service
/usr/share/dbus-1/services/org.freedesktop.Tracker1.service

There is not a lot that can automatically start it but I don't know how 
this works.

But anyway; if all else is equivalent, you can just symlink the new one 
to the old one:

# mv /usr/bin/tracker{,.backup}
# ln -s /usr/local/bin/tracker /usr/bin/

And see what happens.
