The problem is present in the teplate MSSQL by ODBC

Steps to reproduce:

1. In a host monitored by a Proxy
2. Define a Master item (retriving a JSON)
3. Define a Dependent Item
   1. Extracting some part of the JSON with discard vale in Custom on Fail
   2. do not keep history
4. Optionaly defiene a dependent item form the previous dependent
5. The Master item get unsupported
6. All the dependent items get unsupported with the same message than the Master item
7. The master became available but the result does not contains the JSON value for the first dependent item
8. The first dependen item is still in unsupported state, besides the custom on fail
   1. If we change the conf to store history, the item change it state

Expected:

When the master became available, the dependent item should became available, at least in this case.
