Changed ivar/slot name in stateful trait not recognized as a change

[astares]

To reproduce: use latest Pharo 7 (here Pharo-7.0+alpha.build.1139.sha.9fe3ff4d8578d7e53b4d4104254d98ae850a7cc0 (64 Bit))

and run

Metacello new
baseline:'Bootstrap4';
repository: 'github://astares/Seaside-Bootstrap4:master/src';
load

to load Seaside and Bootstrap.

There is a stateful trait "SBSTContextualStyled" with two slots (#modifier. #contextStyle)

Change the name of one of the slots by redefining from

Trait named: #SBSTContextualStyled
uses: {}
slots: { #modifier. #contextStyle }
category: 'Bootstrap4-Core-Traits'

to

Trait named: #SBSTContextualStyled
uses: {}
slots: { #modifier. #foo }
category: 'Bootstrap4-Core-Traits'

and Iceberg will not notice this change.
