Spreadsheet: Don't remove on_change tab function after loading a file

Forgot to remove that in c0c9825f67e649daf277e75829c8f4bce1428115, as
this function was no longer declared and used... Until the previous
commit.

This meant that pressing the F2 key after opening a file no longer
matched the current tab.
