* tests/event.test (_text_ind_to_x_y, _get_selection): Fix

	incorrect use of results from bbox invocation so that
	y center point for a give index is calculated correctly.
	Add new method to return the selection and use it in
	test cases. Always lappend to the result list to avoid
	case where initial result includes a space.
