fix: on rp election, some variables are not reset #233

In some cases, the RP selection mechanism does not work as intended.

For example: with this list of RP:

===============================================================================
Group Address     RP Address       Prio  Holdtime  Type
===============================================================================
232/8             169.254.0.1         1   Forever  Static 
224.1.1           172.16.20.2         0        21  Dynamic
                  172.16.30.3        30       146  Dynamic
                  172.16.10.1        30       146  Dynamic
225.1.1.3/32      172.16.30.3        30       146  Dynamic
                  172.16.10.1        30       146  Dynamic

in the MRT, the RP elected is 172.16.30.3 instead of 172.16.20.2

Nice catch, thank you for taking the time to submit this, and sorry for taking so long to merge!
