QueryInterceptor : Missing value during early rebalance in functional commands

Functional commands, including ComputeCommand, calculate the value to be set or removed inside the lambda when the command is executing. If the value previous value has to be removed for any reason, the value has to be picked up from the context.
In some rare cases, during topology changes, the value might not be in the context and so it can't be retrieved or removed. In that particular case, the method provided by the ISPN-7990 issue has to be used to delete the key in every context.

In this issue, we need to add a reproducer for the problem and correct it.
