mod_lib_ldap: Report bind failures

What steps will reproduce the problem?
1. Setup ldap with a wrong bind_password

What is the expected output? What do you see instead?
I would like to see: "LDAP bind failed - server result: ..."
But I get instead:
mod_c2s: Traceback[c2s]: /usr/lib/prosody/modules/ldap.lib.lua:217: attempt to
