Make diagnostic note for existing method with unsatisfied trait bounds
multiline for cleaner output.

  = note: the method `count` exists but the following trait bounds were not satisfied:
          `[closure@../../src/test/compile-fail/issue-36053-2.rs:17:39: 17:53] : std::ops::FnMut<(&_,)>`
          `std::iter::Filter<std::iter::Fuse<std::iter::Once<&str>> [closure@../../src/test/compile-fail/issue-36053-2.rs:17:39: 17:53]> : std::iter::Iterator`

Before:

Hmm, I mean it's a little better, but I'm wishing we could make the error itself clearer. I'm still not 100% sure is going on when I read either of these errors.

@jonathandturner I agree. I noticed this output while working #41488, but it was unrelated to the problem at hand so created this quick PR.

@jonathandturner - I think this PR fell between the chairs. Do you think it's ready for r+ or are there concerns?

@estebank - can you file a followup issue to further improve this error? With that, I don't mind r+ing this as an incremental improvement. I just don't want to lose that more work needs to happen.

After thinking about this, this looks like a strict improvement over the current state - but I would like a UI test (r=me modulo that). However, we do need to figure out a better way to represent this error. I'll open up an issue about it.

Agree with @arielb1 - ui tests here would help us catch regressions.

Errors look legit. Maybe there are tests that haven't been updated yet?
