Load generic order from database if not already in cache

[marcdoan]

CASE SUMMARY

• Manish's order queue is empty after successfully logging into the Driver App
• The call to getAllAssigned returns the following error:
  class java.lang.Exception-Error - Order g-429 not found

DIAGNOSIS

• Prior to the release of Order Ahead, Houston loads the following orders from MySQL whenever it "resyncs"
  1. All "open" orders (any state except "delivered" or "cancelled")
  2. All "closed" orders on the current day
• With the introduction of Order Ahead, Houston only loads orders for that particular day whenever it resyncs
• Therefore, if a driver forgets to complete an order (or the dispatchers forget to "clear" out-dated orders), an order from the previous day will still be in the driver's order queue but not loaded by Houston after a resync (and thus missing)

PROPOSED SOLUTION

• Lazy-load generic orders. If a generic order is not found in Houston's cache, load it from MySQL regardless of which day it was created on
