fix: updated mebrains parcellation name

[xgui3783]

Name (and ID) of mebrain parcellation has been updated at FZJ-INM1-BDA/siibra-configurations@614ecce7 .

This PR updates the test to reflect this change.

[xgui3783]

The failed tests seems to be due to two things:

1. @AhmetNSimsek also noticed when running it on his local machine

      Error using arrayfun
      Non-scalar in Uniform output, at index 7, output 1.
      Set 'UniformOutput' to false.

2. getParcellationMap (Unfortunately, not very adept at debugging matlab code, so following is a lot of conjectures)

https://github.com/FZJ-INM1-BDA/siibralab/blob/xgui3783-patch-1/%2Btest/TestParcellations.m#L32

            julich = siibra.getParcellation("human", "julich 2.9");
            labeledMapMNI = julich.parcellationMap("MNI Colin 27").fetch(); # this line

calls https://github.com/FZJ-INM1-BDA/siibralab/blob/xgui3783-patch-1/%2Bsiibra/%2Bitems/Parcellation.m#L59

        function map = parcellationMap(obj, space)
            map = siibra.items.maps.ParcellationMap(obj, space); # this line
        end

end up calling https://github.com/FZJ-INM1-BDA/siibralab/blob/xgui3783-patch-1/%2Bsiibra/%2Bitems/%2Bmaps/ParcellationMap.m#L13-L16

        function obj = ParcellationMap(parcellation, space)
            obj.Parcellation = parcellation;
            obj.Space = space;
        end

My understanding is that the string "MNI Colin 27" end up passing to ParcellationMap, as if it is a Space object. Somewhere along the chain, we would have to call "fuzzyMatch" (?)

(We have have a similar issue with Region.continuousMap)

[AhmetNSimsek]

  Error using arrayfun
  Non-scalar in Uniform output, at index 7, output 1.
  Set 'UniformOutput' to false.

This seems to be triggered due to superficial fibre bundles. I bypassed it atm to check the issue 2

[AhmetNSimsek]

I noticed that spaces of julich brain 2.9 is not populated for some reason:

Id: "minds/core/parcellationatlas/v1.0.0/94c1125b-b87e-45e4-901c-00daee7f2579-290"
Name: "Julich-Brain Cytoarchitectonic Atlas (v2.9)"
Atlas: [1×1 siibra.items.Atlas]
Modality: "cytoarchitecture"
Description: ""
RegionTree: [1×1 digraph]
Regions: [1×578 siibra.items.Region]
Spaces: [1×0 siibra.items.Space]

[AhmetNSimsek]

It seems one has to supply a Space object instead of a string to <parcellation>.parcellationMap(Space).

@valentin-pinkau and @xgui3783 Is this the intended design? Shall we bring fuzzy matching back?
