Tab Renaming Function Should Use Rename Symbol

When I use Tab to rename a function, it should do it as Rename Symbol.

As it is now, if I use Tab to rename a function then I have to go find all the previous - and now broken! - references. Once I’m in the particular files that have the broken references Tab will THEN help me by renaming the functions, but this is “fake” help. It should have just renamed the symbol.
