Issue type: :bug: Bug

Description

Entity IRIs must be url encoded to be valid
When applying grel:toLowerCase to iris using the shortcut syntax, the URL encoding is stripped from the value the function is applied to.

Steps

take input:

country_label: "United Kingdom"

Apply following yarrrrml mapping to source field with mapping from input:

          s:
             function: grel:toLowerCase
             parameters:
                - [ grel:valueParameter, prefix:country_$(country_label) ]
           po:
             - [ a, prefix:Country ]

error returned: The subject "http://www.prefix.com/country_united kingdom" is not a valid IRI. Skipped

However, if I write the mapping without shortcuts the output is as expected. See below. Full mapping without shortcuts:

    s:
      function: grel:toLowerCase
      parameters:
        - parameter: grel:valueParameter
          value: prefix:country_$(country_label)
    po:
      - [ a, prefix_country ]

expected output: <http://www.prefix.com/country_united%20kingdom>
