Revival of globally-settled assets should depend on ICR but not MCR

[abitmore]

User Story

As a user I'd like that the globally-settled assets get revived only when CR of existing collateral bids plus the settlement funds exceed ICR but not only MCR, so that the new debt positions after revival would be farther away from being margin called.

I don't think ICR should be considered here, MCR is enough.
Revival is old debt -> MCR
