  Fix image MC loading glitch in image build scripts when checking package-cache.

MCRepository>>includesVersionNamed: does not check explicit version name,
so this may do the wrong thing when checking the cache:
    version := ((MCCacheRepository default includesVersionNamed: latestVersion)
        ifTrue: [MCCacheRepository default]
        ifFalse: [repository]) versionNamed: latestVersion.

Therefore do this instead:
    version := (MCCacheRepository default versionNamed: latestVersion)
        ifNil: [repository versionNamed: latestVersion].
