fix(test3): RunMemPackage on p/leon/avl to restore types

[thehowl]

		// XXX(morgan): test3 specific, there is a bug with the transactions and
		// the way test3 runs.
		// The theory is as follows:
		//     Take a look at defaultStore.SetType
		//     When p/leon/avl was called, a type with the same TypeID was found in the cache, but it was different than the ones passed, so the function returned
		//     But the type was never in the store
		//     The reason this can happen is that up until this recent commit
		//     https://github.com/gnolang/gno/commit/8afb1a42e138014a3025ef4817aff67b6f4f7ded
		//     The store caches were shared with all child stores, even the ones that are eventually rolled back (due to, like, a failing transaction)
		//     So, in the running node, in a first addpkg, the type was saved in the cache, but then there was a bug in the code so the transaction failed
		//     The type is now in cacheTypes, but not in the database
		//     Afterwards, it was re-uploaded. SetType is called, it detects an existing type in cacheType, but the types are different; so SetType returns without storing it in the database
