bug: $RouteAssignment merge syntax does not resolve correct url

[techfg]

The following code does not properly interpolate the recordid in context - {recordid} is in the resulting string instead of the actual recordid guid.

context.addRecordDataFrame({
    recordid: s.getIdFieldValue(),
}).merge(`$RouteAssignment{username/appname:collectionname:detail}`)),

Actual Result
/workspace/username/appname/dev/app/username/appname/collectionname/detail/{recordid}

Expected Result
/workspace/username/appname/dev/app/username/appname/collectionname/detail/0194146a-e8f3-7e1f-8b35-e7949dd41698
