Abandoning claim through tx list results in empty tile in Downloads

[tzarebczan]

The Issue

If a user abandons a claim using the trash icon in the tx list, the claim is deleted but the file is not removed from LBRY and thus creates a blank tile on the Downloaded list (after accessing the claim once or reloading LBRY). The claim revoke prompt should allow the user to delete the file from LBRY or should just do it automatically (not sure you'd ever want to keep the file in file_list if you are revoking the claim)

Steps to reproduce

1. remove a published claim via the tx list, wait for block confirmation
2. go into the downloads area, you will see the published tile
3. click tile - will show the URL and shows that there is nothing at this location
4. Go back to Downloads folder - now tile will be blank

Expected behaviour

Delete file automatically or prompt user

Actual behaviour

File shows in Downloads as blank tile

System Configuration

If a file exists, we should give the user an option to delete the file from LBRY (and locally if they want) when abandoning a claim.

This effort would probably start around #895

This is no longer an issue, we don't show invalid claims. And Claim abandon will now allow for a delete flag we can pass.
