This pull request fixes a crash when AliSim simulates alignments using GHOST with partitioned/mixed-datatype models because of a deleted tree pointer. This bug was reported in the iqtree2 repo.
Solution: set the pointer to the correct (newly-created) PhyloTreeMixlen tree.

…ation reported at #537 (in the iqtree2 repo) because of a deleted tree pointer

Hi @trongnhanuit,

This issue has already been solved in #182 in a much more general way. No need for a duplicate solution.

Best,
Stefan

I understand that this issue is also solved in another PR #182 , but since this one is much easier tor review, I'll merge it first.
