Matcher seems to lose params and javadoc info when moving members

Can you still reproduce the issue with the latest commit? If yes, I'll look into it

[liach]

Hadn't worked on Minecraft since the chat report ban system was added.

You can try reproduce it yourself by:

1. Find an update where, say, mojang moved out a method by elevating (e.g. the recent Loot table refactor, the resource refactor a while ago)
2. In the base version, add parameter names and javadoc to the method to be eleveated
3. Perform a match, and see if the resulting method keeps the parameters and javadocs

Fyi, in enigma format, params and javadocs are members of method entries. Maybe matcher forgets about these children entries when it moves methods.
