MDEV-34998: master can stop responding after cluster vote to evict a node

Browse Source 
After cluster vote to evict a node that failed a transaction,
current master can't commit anymore.

Error voting for joiner in the JOINED state was broken because
the group-wide commit cut (implicit SUCCESS vote) was not taken
into account when processing error vote request from the JOINED
node.

This commit adds 3 MTR tests to verify the fix in the galera
library works as designed.

Requires Galera library commit 91f0090a05e96c3cc353b80d961ede45cefb9279
(galera library version > 26.4.19).
