Currently, a consumed variable in a try block can't be consumed in the associated else block, even if the variable isn't consumed in the erroring path of the try block. For example:

actor Main
  new create(env: Env) =>
    try
      partial()
      consume env
    else
      consume env
    end

    fun partial() ? => error

If we enter the else here, env wasn't consumed in the try, but the compiler says we can't use a consumed variable.

The compiler should find the last erroring operation in a try and ignore anything happening after it when checking consumed variables in the else.
