Support classic accounts and trustlines in snapshots

[JakeUrban]

What version are you using?

22.0.0-rc.1

What did you do?

Created a snapshot like so:

stellar snapshot create --address $myaccount --address $contractid 

Then used the snapshot to create an environment for my contract test using Env::from_ledger_snapshot_file.

Because $myaccount is a Stellar account, and the function tested on $contractid results in a SAC transfer, the test failed with the following:

topics:[error, Error(Storage, MissingValue)], data:"trying to get non-existing value for contract instance"

This appears to be because trustlines are not saved to the snapshot file or are not loaded when creating the environment.

Requires some investigation. Snapshots are supposed to include all the trust lines of an account when an account is specified.

For example:

stellar-cli/cmd/soroban-cli/src/commands/snapshot/create.rs

Lines 284 to 286 in 90db678

	let keep = match &key {
	LedgerKey::Account(k) => current.account_ids.contains(&k.account_id),
	LedgerKey::Trustline(k) => current.account_ids.contains(&k.account_id),
