alter_field() fails to drop indexes on columns with mixed case on Oracle

On fields that set db_column with mixed case, alter_field() fails to drop indexes on Oracle.

Due to Oracle's uppercases_column_names feature, get_constraints() returns all columns as lower case. However, alter_field() use of _constraint_names() compares the column name as set by db_column. This must be accounted for on Oracle for the index to be properly dropped.
