resolve: keep wlock while resolving
This will make resolve use correct locking and thus make it more safe.
Resolve is usually a long running command spending a lot of time waiting for
user input on hard problems. It is thus a real world scenario to start multiple
resolves at once or run other commands (such as up -C and merge) while resolve
is running. Proper locking prevents that.
