Fix Easyshare not to display versions among suggestions

There are 3 ways to share a document using Easyshare. 2 ways display only "main" document, the third displays also the versions of the documents. This display of versions should not happen in Easyshare.

To reproduce this issue, use nuxeo 9.10 + JSF

1. Create a File document and version it with different pictures each time to differentiate the versions by binaries
2. Create an EasyShare place
3. In the EasyShare place, use the book icon to add a document to this collection and look at the documents proposed: all versions are displayed (and no way to differentiate them)
4. Adding any version will add the working copy, which is right and OK.

Expected: only the working copy should be given as a choice.

Potential issue: missing "and ecm:isVersion = 0" in NXQL query

Nota Bene: In WebUI, this way to add a document to an EasyShare location does not seem to exist.
