BSON::ObjectId#inspect returns a string that evals into an object id

`BSON::ObjectId('559acc9e546f6e09418d0200')` will now pass the
given string to BSON::ObjectId.from_string and return an equivalent
object id.

This change will allow for copying and pasting object ids without
having to use `#to_s` and `.from_string`, which would be nice when
working between different terminals
