Session.execute() method is not wrapped by wrap_db_error

[Boris Pavlovic]

Session.execute() is called when we are calling Query.update() method. Without wrapping Session.execute() all exception that raises Query.update() wouldn't be wrapped by wrap_db_error() method.

    Fix missing wrap_db_error for Session.execute() method

    We should add wrap_db_error for Session.execute() method, because
    Query.update() method will call Session.execute() and it is not inside
    Session.flush(), so exceptions from Query.update() wouldn't be wrapped.

    Add test for Session.flush() wrapper
    Add test for Session.execute() wrapper

    Fixes bug 1107890
