Support schema selection in cdr_adaptive_odbc
Asterisk now supports using ODBC with databases where a single schema must be
selected. Previously, INSERTs would fail because they did not take into
account extra fields cause by having multiple schemas. This also corrects
some SQL resource leaks.
(closes issue ASTERISK-17106)
