When looking for table or database names inside INFORMATION_SCHEMA
we must convert the table and database names to lowercase (just as it's
done in the rest of the server) when lowercase_table_names is non-zero.
This will allow us to find the same tables that we would find if there
is no condition.
Fixed by converting to lower case when extracting the database and
table name conditions.
Test case added.
