warning when preferred package is not loaded

[GildasLepennetier]

Hi there,

Noticed something that may help the development of this package. Did not find that in the closed or open tickets.
The following code should be self explanatory

library(conflicted)
conflicts_prefer(config::get)
get

The result of the following is "<environment: namespace:base>" for the usage of "get" since the library "config" was never loaded. This may create unexpected behaviour without a warning like "warning: usage of a function from a different library than the preferred one: base::get instead of config::get"

I do not know if this is possible, or in the scope of the development plan of the conflicted library, but I think it could be a great improvement.
