Added an unit test to check if:

1. before tax split logic upgrade height, all taxes go to burn module
2. after tax split logic upgrade height, 50% goes to burn module, 50% goes to community pool (50% is split percentage)

@inon-man @ZaradarBH @edk208 can you confirm that it is the correct unit test. I am not sure if I understand the split logic correctly and fully.

I can find param query for burn_tax_split in the commits. Is it intended?

I think it is normal to be able to query all params

I meant I could not find cli and rest query for the parameter unlike the all other treasury parameters.

you can find it here for burn_tax_split. This is after upgrade test.

I am aware of it but my question was there is no separate query for burn tax split like othe params for keeping the consistency. However, I am okay with not having it because there is no such consistent pattern between modules in Cosmos SDK.
