### REAKING CHANGES
- return an invalid iterator if the user try to use next or prev without
having set the initial location of the iterator:
- calling next, and prev without having put the iterator at a specific
key or location (first, last) will now return the tuple `{error, invalid_iterator}`
- fix crash when moving to next key on a new iterator.
- fix behavior of Refresh. Refresh is supposed to reset completely the
state of the iterator. Fix test accordingly.
- `transction_get/2` has been removed, and is replaced by `transction_get/3` with the third argument to spass the options.
- `transaction_get/3` to get using a column family is now `transaction_get/4`
