Fix bad advice in cook book (#2308)

This line directly contradicts the warning that google mock spits out on unused mock calls:
```
NOTE: You can safely ignore the above warning unless this call should not happen.  Do not suppress it by blindly adding an EXPECT_CALL() if you don't mean to enforce the call.  See https://github.com/google/googletest/blob/master/googlemock/docs/CookBook.md#knowing-when-to-expect for details.
```
One or the other should be changed, and I believe the advice in this file is incorrect.

 will print a warning about the "uninteresting call". The rationale is:
 
   * New methods may be added to an interface after a test is written. We shouldn't fail a test just because a method it doesn't know about is called.
-  * However, this may also mean there's a bug in the test, so Google Mock shouldn't be silent either. If the user believes these calls are harmless, they can add an `EXPECT_CALL()` to suppress the warning.

 warnings, while sometimes you may want the opposite, i.e. to treat all
