mergestate: remove unnecessary clearing of `localctx` and `otherctx`
As noted in the previous commit, there are no callers that (re-)use
the instance after calling `reset()`. There are also no callers that
call `_read()` after doing anything with the instance (it's only
called right after an instance is created).
If reviewers feel that this is too risky, I can extract and reuse the
poisoning code that indygreg once added for poisining repo instances.
