Tiered Vote and previous map exclude

[Xiaminou]

I have a server on Empires mod and I use UMC for map votes. I wanted to use UMC's tiered vote so my players can vote between different type of maps, however I also use map exclude to exclude a large portion of the previously played map.
I have found that when one of the two groups I have run out of maps it will properly make players vote between maps in the the other group as the first vote, however when that vote is complete instead of changing to the vote map it thinks that the map that was voted is not a map but a group instead and it looks for maps in that group.
L 05/26/2018 - 02:07:22: [umc-core.smx] KV Error: Unable to find map group "0". Try removing any punctuation from the group's name.
This is an extract from the error logs, it looks for a group named "0" which is in fact the min_players for the map that was voted.

After recently discovering UMC and working on fixing it for my HL2:DM server (where I use Tiered voting mode too), I took one hour to analyze, nail down and fix this issue: Adrianilloo@d15e8e2.

The problem is that the "raw" map vote result handler wasn't set to be used when Tier/Group votes initially fail due to these exclusions (and raw Map vote is created instead).
