HasRightAction can be passed a base context as a parameter. If not, it assumes "/application" and asks the specified RightManager if the user has the right on this context.
All the existing right manager prepend the passed context with the specified context prefix.
Default and Web context prefix already return "/application" or "/application/...", so the full context is "/application/application/..." and the RightManager always return false.

To resolve this, the default base context value for HasRightAction should be the empty string.
