[Closed in favour of !3104; V121-specific] Disallow MsgSend to network module LendingName and AffilicateCollectorName

[Closed in favour of !3104 (merged)]

[V121-specific]

Intended to close #1665 (closed)
'LendingName is not on the list of MsgSend-disallowed network modules'.

This can be closed by the slightly-larger !3104 (merged)
'Do not allow network modules as memo final destinations'
which includes the same effect.
