Fixing removal of entry locks

Multipage screens did not remove locks when no values were being saved.
And the All Done button submission seemed to go ahead without waiting
for the async: false call to complete.  Now the submission is held off
until after the locks are cleared for sure.
Kill locks 1st after no change on multipage form

So, when the page change event happens, and nothing has been altered on
the page, then the removeEntryLocks function is called, with params that
will trigger the ajax loading of the page after the locks have been
removed.  The ajax loading actually happens in the
formulize_javascriptForAfterRemovingLocks function.
Avoid passing parameters that can be created by the function that uses them.
