Title: Only manage Lead Organisations in speed tagging

there was an issue with saving organisations from the
speed tagging interface. modifying that fields was giving
an error - "Lead organisations at least one required".

this was caused because the assignment was not setting
the `lead` attribute on edition_assignments to true. later
we decided to only allow modification of lead orgs from
speed tagging interface, so here it is.
