Re-position RescuedExceptionInterceptor middleware

[st0012]

Currently, exceptions raised by middlewares placed between RescuedExceptionInterceptor and DebugExceptions are rescued DebugExceptions without anyway to be reported to the CaptureExceptions middleware.

By placing RescuedExceptionInterceptor closer to DebugExceptions, it should avoid similar issues.

Closes #1563
