loadmodel! example in the docs doesn't work

[jonathanBieler]

The docs (http://fluxml.ai/Flux.jl/stable/saving/) say you can load a model with :

model = loadmodel!(model, @load("mymodel.bson"))

but @load("mymodel.bson") returns nothing.

I think it should be something like loadmodel!(model, load("mymodel.bson")[:model]). Also it looks like this case is not tested (can't find it in test/utils.jl).

Flux v0.13.11 & BSON v0.3.6

Good catch, mind filing a PR?

Will do.
