PlugInSingleRowFunction and stream property name conflict

[zhucj1981]

When PlugInSingleRowFunction's name and stream property name are same, compiler will treat property name as function.

		Map<String, Object> columns = new LinkedHashMap<>();
		columns.put("id", String.class);
		configuration.getCommon().addEventType("bar", columns);
		configuration.getCompiler().addPlugInSingleRowFunction("id", "Test6", "id");

 					"create schema A (id string)",
 					"insert into A select id from bar"
					};
			for(String epl:epls) {
				EPCompiled compiled = epCompiler.compile(epl, arguments);
				arguments.getPath().add(compiled);
			}
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

Since this change can affect EPL behavior it is labeled for next major release.
