Screen __index: Don't turn argument into a string

Browse source 
Calling lua_tostring() on a number/integer, turns that stack slot into a string.
This patch changes the code to only call lua_tostring() if the function argument
really is a string.

This partly also caused https://github.com/awesomeWM/awesome/issues/238.
