#574 added an out arg to `SolutionComponent.TryRemoveSolution` containing the solution that was removed. I made this change since I thought there was no way to get the removed solution for further use. Didn't notice `SplitSolution` which provides nearly the same behavior. With this PR I want to remove that out arg from `TryRemoveSolution` to keep the SolutionComponent API simple and to avoid having multiple ways of doing things. Existing code uses `SplitSolution`, I just wasn't paying attention.
Feel free to deny merging this if I'm over thinking it. I think it'll help keep solution code from becoming a mess.
