Grails: when adding a dynamic property to a gsp file, class' package prefix is not inserted to "Property type" field on Code Completion

*Build 110.502*

Consider there is a domain class **foo.Book** and its views.
Open show.gsp file.
Alt+Enter on unresolved **bookInstance** -> Add dynamic property.
Type **Boo** in **Property type** field, invoke Completion, choose **Book (foo)**.

Result: no package prefix is inserted; "Type 'Book' is not resolved" message is shown.

Note 1: when invoking Code Completion for some library type, package prefix is not inserted either, but the type is resolved.
Note 2: when adding dynamic properties from groovy files, package prefix is inserted on Code Completion.

Reproduce the issue in show.gsp using the unresolved bookInstance and the Add dynamic property action, then inspect the code-completion path for the Property type field. Verify completion with foo.Book inserts the package prefix and resolves the type, while preserving the existing behavior for library types and dynamic properties from Groovy files.
