fix: add index on tracker_field(original_field_id)

This query is executed when a tracker admin edits a tracker field in form element administration. Without this index on platforms with 1M+ form elements, it can take up to 6s. With the index it's down to 15ms and the page is no longer slow to render. Closes request #24165 Modification of a tracker field is slow Change-Id: I11d19e1d26e265e319d1f2c06edda9046554bf26
