Removing useless rescue clause on Timeout middleware

[HugoLnx]

Just removing a useless rescue clause from Timeout middleware. When I coded this method in the project I worked with @emerleite, I didn't know that catch also works for raised exceptions.

PS.: No test added because this is a refactoring, this code are already tested on: timeout_test.exs#L99

Fixed during other changes so this is not needed anymore. Thanks!
