SB line coverage for collision reporting in CFE_SB_SubscribeFull requires alternate config

[skliper]

Is your feature request related to a problem? Please describe.
Default config doesn't use the hash implementation, so there's no way to get collisions:

    1129         [ -  + ]:        451 :     if (Collisions != 0)
    1130                 :            :     {
    1131                 :          0 :         CFE_EVS_SendEventWithAppID(CFE_SB_HASHCOLLISION_EID, CFE_EVS_EventType_DEBUG, CFE_SB_Global.AppId,
    1132                 :            :                                    "Msg hash collision: MsgId = 0x%x, collisions = %u",
    1133                 :          0 :                                    (unsigned int)CFE_SB_MsgIdToValue(MsgId), (unsigned int)Collisions);
    1134                 :            :     }

Code Coverage is not possible. "Collisions" is always set to 0.
To set collision the following path is taken:

1. Initialize Collisions = 0 -> CFE_SBR_AddRoute (Not A Stub) -> CFE_SBR_SetRouteId (in cfe_sbr_map_direct.c)

CFE_SBR_SetRouteId is how "collisions" is set but it will always return 0.
