Lack of ChannelData schema validation in InitializeMessageRecoveryCommand

[ishantiw]

Description

The ChannelData provided by the user in the InitializeMessageRecoveryCommand command is decoded but not validated. The inclusion proof prevents rogue values from being used (although a malicious chain could create invalid accounts). We also note that passing the empty string value to trigger a non-inclusion proof is possible, but the decoding would fail in the execute method.

Which version(s) does this affect? (Environment, OS, etc...)

v6.0.0-beta.2
