Bug: EscrowTransaction table Inconsistent

[andy-shi88]

Description

There is an inconsistency in the escrow_transaction table, in the timeout and block_height field.

This can cause invalid snapshot file hash later when generated.

Causes:

• download block behaves differently than generate or broadcast tx, in download block the timeout field is already incremented with the said current block height,
• when applying escrow transaction in download block, it should not increment the timeout again.

Solution:

• breaking change:
  • insert timeout field as client fill and calculate expiration on the go.
