Steps to reproduce:

• Add a layer with a workspace with "." in the name.
• Open the feature grid.

Result:

• The attributes are not visible

This because when trying to get the featuretype name, doing this

get(state, "query.featureTypes." + get(state, "query.filterObj.featureTypeName") + ".original"

get(state, "query.filterObj.featureTypeName") returns it.geosolutions
is the same of get(state, "query.featureTypes.it.geosolutions"), that is wrong.
We should replace the concatenation with "[...]" to fix it.
