racer-find-definition can't be called non-interactively

[Hi-Angel]

Steps to reproduce

1. Open test.rs with the following content:

   fn func() {}
   
   fn main() {
       func();
   }

2. Enable racer-mode

3. Place caret over func() call inside main, press M-:, type (racer-find-definition), press Enter.

Expected

Point should've jumped to fn func() {} on the 1st line, the same as it would if the command was executed with M-x instead.

Actual

Point doesn't move.
