CollectionRowBlock column names hid class attributes with the same name

If a CollectionRowBlock has a column with the name "collection" or something like that, the column accessor will replace the original class property "collection".

Example:
We have a CollectionRowBlock `rowBlock` with a column "collection" that has a value "test". When you run `rowBlock.collection` you would expect it to return the actual parent collection this RowBlock belongs to. Instead it would return "test".

Start by locating CollectionRowBlock and the column accessor that handles names such as "collection". Reproduce the example with a column named "collection" and verify that rowBlock.collection still returns the parent collection rather than the column value, while other column access remains usable.
