Proto: Enable transferring tickets between implicit accounts

Context

This MR enables implicit accounts to transfer tickets to other implicit accounts. With this change, Transfer_ticket manager operation adjusts ticket balances even if the destination points to an implicit account and, thus, enabling implicit accounts to receive tickets from other implicit accounts.

Manually testing the MR

This work enables transfer tickets commands to target implicit accounts. The way to use it is as follows.

octez-client transfer 1 tickets from 'tz1...' to 'tz1...' with entrypoint 'default' and contents '"2022-11-03T05:53:18Z"' and type timestamp and ticketer 'KT1...'

Notably, now you can transfer tickets from one tz1 address to another, except that the entrypoint parameter must be %default.
