Let a clone proceed on a date shift with no dimension override

Browse Source 
The panel required at least one override for both recode and clone. For
recode that is right -- rewriting rows as themselves does nothing. For clone
it is not: copying prior year forward changes the dates and, through
dim_period, the season and month dimensions, which is the entire point of
cloning from a reference segment. The server-side requirement was dropped
when from_logid went in; this one was missed, so the operation was blocked
in the UI with "Enter at least one override value".

Clone now only has to be doing something -- an override, a shift, or a
factor other than 1 -- and says so when it is doing none of the three.
