Units for edit of first purchase of a new tem default back to ampule

[mnorbeck]

1. create a new item. Enter minimal data: change all units to "each", enter a quantity. Save.
2. on the new item, edit that first purchase. Notice on dialog Units default back to ampule

Also, after a location adjustment (Remove), the edit purchase dialog no longer displays the unit.

See 9 inch washclothes vs 7 inch washclothes in beta site. 9in show this issue, 7 in no longer shows units in edit purchase dialog

Closing this bug because we removed the edit purchase screen (purchases can be adjusted via inventory adjustments).
