Fix #1212:

 - Updated pj_register_strerror() to just return PJ_SUCCESS when the same range
and handler is being re-registered.
 - Removed the usage of static flag of error string handler registration in some
modules, which prevent the re-registration of the handler, e.g: in restarting
pjsua, as such flags never got reseted.
