iamamyth 8c43e33e35 logging: Fix easylogging++ init with blank config
The upstream version of el::base::TypedConfigurations::unsafeGetConfigByRef
accesses uninitialized memory if a key doesn't exist.
Commit b2c59af84de8d35c1eee38878053206a62756968 patched the library to
throw in this case, avoiding the invalid access, but the more suitable
pattern, both logically, and as evidenced by the behavior of
unsafeGetConfigByVal, would be to return a const reference to a
default-initialized value with static storage duration.
