While setting up some programmatic configuration I stumbled upon a bug where the copy function of LocalSearchPhaseConfig doesn't copy deep enough.

We were setting up the template before modifying the configuration at runtime according to the instructions we noticed that we were mutating the MoveSelectorConfig of the template.

I've created a couple failing tests for this behaviour (one including the config copy ctor, and one with the minimum reproduction). 

We've not explored if more fields are affected by this issue.

We've worked around it by just creating the MoveSelectorConfig from scratch each time instead of appending to our xml-based template.
