Loading baseline with package on SmalltalkHub signals MessageNotUnderstood

[Rinzwind]

The following defines and loads a baseline with a package on SmalltalkHub, which works in Pharo 11 (build 733), but signals a MessageNotUnderstood (“Instance of MCSmalltalkhubRepository did not understand #isCacheable”) in Pharo 12 (build 1550):

Author useAuthor: 'Anonymous' during: [
	(BaselineOf subclass: #BaselineOfExample instanceVariableNames: '' classVariableNames: '' package: 'BaselineOfExample')
		compile: '
			baseline: spec
				<baseline>
				spec for: #common do: [
					spec package: ''CSV'' with: [
						spec repository: ''http://www.smalltalkhub.com/mc/JohanBrichau/CSVParser/main'' ] ]' ].
Metacello new
	baseline: 'Example';
	load.

I do realize we’d better stop using SmalltalkHub, but this nevertheless seems like a bug that should be fixed.

Thanks! I'll check it!
