Improve action 'Copy Document'

When using the copy-document action in the CMS, we've encountered a number of annoyances:

1. Make the current location default location for the 'pasted document' (instead of /document) (see screenshot 1)
2. When pasting (to a different location) is done, we would expect the pasted document is the 'active' one (see screenshot 2)
