Method count is not callable in untrusted context (totalCount)

[mhsdesign]

I get an error in combination with Flowpack Simple search at line:

Flowpack.Listable/Resources/Private/Fusion/PaginatedCollection.fusion

Line 31 in 0dfe9e2

totalCount = ${Type.getType(props.collection) == 'array' ? q(props.collection).count() : props.collection.count()}

props.collection has changed in Flowpack.SimpleSearch with this pr:
https://github.com/Flowpack/Flowpack.SimpleSearch.ContentRepositoryAdaptor/pull/39/files#diff-ffc206e78cb0c19096185c41a6daf40384dee16565b7a919e5438c6ce1d2cb7fR223

and is no longer a simple array but and \ArrayIterator or better a \Traversable

the fusion in totalCount should be changed to account for \Traversables

a current workaround is to call Array.values on props.collection before passing it to Flowpack.Listable:PaginatedCollection
