unintuitive behaviour for vh execution delete

[ghost]

Using vh execution delete 1 2 3 ... or vh execution delete a-b multiple times to delete for existing executions a-b will continue to return the messages

...   Deleteing #a...
...   Deleteing #a+1...
...   Deleteing #a+2...
----
...   Deleting #b-1...
...   Deleting #b...
:)  Success! Deleted 8 executions.

Even after the execution has been deleted. This could be misleading, and give the idea that an execution didn't succeed as stated. It might be more informative to change this behaviour to

...   Discovering #a...   #a exists!...  Deleting #a....
...   Discovering #a+1...  #a does not exist (skipping)...
----
:) Success! Deleted [n1] executions. (Note: [n2] executions did not exist)
