Caused by implementing ZBX-4296

As we know disabled hosts missing in the server configuration cache.
So, when gui tries to ask server to execute a script for a host which is disabled in gui, the server immediately responds with "red" ERROR:
Unknown Host ID [10054]

Debuglog shows (the hostid=10054 is disabled):
16049:20120418:203158.324 Trapper got [

{"request":"command","nodeid":0,"scriptid":"5","hostid":"10054"}

For an enabled hostid=10017 Debuglog shows:
16049:20120418:203232.804 Trapper got [

I see two possible solutions:
1. discard changes in ZBX-4296 (bad)
2. allow server to not use configuration cache when executing gui scripts (good one)

But main question - how the ZBX-4296 has been tested before closing?
