Simplify managment of test_server_loc

Before line numbers were included in exceptions (in R15), there were
parse transforms and macros that would keep the test_server_loc
process dictionary variable updated; therefore there is a mod_loc/1
function that will normalize the representation of locations.

Simplify the code as following:

* 'test_server_loc' should always contain a list with one or more
  tuples. ({M,F} or {M,F,Line})

* At the beginning of each test case, set 'test_server_loc' to
  [{Module,Func}] of the the currently executing test case.

* Stop updating 'test_server_loc', except when an exception occurs.
  (It used to be updated when running 'init_per_testcase' and so on.)

* Remove the mod_loc/1 function.
