Address book - "Send" button in read only mode

[francovenica]

In the address book, hovering the entries, the "Send" button is shown for people not connected to the wallet and non-owners.
You cannot actually submit the Tx, but still the button should not display in this case.

The greyed-out send button on the top is fine, but we should not display the send button on hover in the address book.

checked the PR1300, the button is no longer present for people who are not logged in, but the icons for editing and deleting an entry are not centered in the line (they are too high in the row)
