Minor code clean up

Routes

• Should the constructor be final?

DefaultRoute

• Add toString which makes easier to identify route in the debugger

StringUtils

• Should probably have a private construtor.

DefaultRouter

• Does SecurityProvider really need the @Inject annotation? Is it not covered by the constructors @Inject.

RouteBuilderImplTest

• testWrongException_type method name is inconsistent with naming and should be changed.

RoutesTest

• Add test for exception route order see example
