[BUG] v12.2.5 There is a debug output statement '()' in the mvc.logController method and the main branch has been checked. If it is indeed a debugging task, it should be possible to delete it, and I have also synchronized the PR,

Describe the bug
Since upgrading to the iris framework v12.2.5, a strange "() () ()" debugging information output has been discovered. Today, I had time to debug the output and found that it came from the mvc library. Therefore, I think it would be great if it were indeed debugged and deleted, so I have already submitted the PR.

To Reproduce
In theory, defining an mvc route is sufficient, as my project has a lot of code and I haven't had time to add use cases yet

Please make sure the bug is reproducible over the main branch:

$ cd PROJECT
$ go get -u github.com/kataras/iris/v12@main
$ go run .

When debugging again and it is found that the output is not pure mode, further exploration is needed.
