bug when lakes is true

[laurenebouaziz]

when running with the dev install on the master branch, I get the following error for a model where lakes=true:

┌ Error: Wflow simulation failed
│   exception =
│    UndefVarError: initialize_natural_lake not defined

If I look at the code, I indeed see in sbm_model.jl:
initialize_natural_lake(config, nc, inds_riv, nriv, pits, tosecond(Δt))
https://github.com/Deltares/Wflow.jl/blob/3bdad55970955e18dcdb8820aa4edce5c9a98668/src/sbm_model.jl#LL92C13-L92C13

however in reservoir_lakes.jl, the instance is called:
function initialize_lake(config, nc, inds_riv, nriv, pits, Δt)
it was recently renamed without the "natural"

Wflow.jl/src/reservoir_lake.jl

Line 232 in 3bdad55

function initialize_lake(config, nc, inds_riv, nriv, pits, Δt)

I think this might be related to the recent changes in the lake module but now it seems not to be consistent anymore, or am I overlooking something?
