The genesis header doesn't have the BABE pre-digest and we insert `0` as slot number. The slot lenience calculation will return the maximum in this situation. Besides returning the maximum which is not bad at all, it also prints some a debug message that can be confusing in the first moment. To prevent printing this debug message, we now just return early when we see that the parent block is the genesis block.

License
- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (
/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
