Mantis #7567. One of the reported log messages showed this:

09:38:40 - [LOGHTTP]: Slow handling of 15572 POST /CAPS/b12c7e98-8261-4953-b7d1-1c414c9893fc FetchInventory2 8acfbca3-13b5-434f-898c-5f4bbe8a76ff from 92.237.199.112:60083 took 62391ms
FetchInventory itself wasn't taking advantage of the new inventory API. This commit fixes that.
