Paste button behavior in Search content views

The filter for the Paste action could use some tweaking in use with Search content views.

To illustrate:

• make a new Workspace ws1
• make two new folders fol1 and fol2 and three files f1, f2, f3 in ws1
• go to Default Search, do text search for file, select f1, f2, f3 in results
• do text search for fol and get the two folders as search results. Paste button will be enabled in the search results view. Select fol1 and click Paste – f1, f2, f3 end up pasted in fol2
