Fix null value in committee name in ofec_sched_e_mv

[hcaofec]

What we’re after

Null value in committee name column in ofec_sched_e_mv will return incorrect results when searching schedule E by committee ID/name text.

Because the committee name column is always null in SE base table, cmte_name has to be pulled from other table.
