Not all packages loaded

[mayer79]

Describe the bug
When using foreach on Windows, not all packages are automatically loaded.

Reproduce example

Two examples: one with "ranger", one with "mgcv":

library(ranger)
library(doFuture)
library(foreach)
library(doRNG)

# Set up parallel backend
registerDoFuture()
plan(multisession, workers = 2) 

# Package "ranger" seems not loaded
fit <- ranger(Sepal.Width ~ ., data = iris)
predict(fit, iris[1, ])$predictions

foreach(i = 1:10) %dorng% predict(fit, iris[i, ])$predictions

# Error in { : 
#     task 1 failed - "no applicable method for 'predict' on object of class "ranger""

# Works
foreach(i = 1:10, .packages = "ranger") %dorng% predict(fit, iris[i, ])$predictions

# Now, this works as well
foreach(i = 1:10) %dorng% predict(fit, iris[i, ])$predictions

# Package "mgcv" seems not loaded
library(mgcv)
fit <- gam(Sepal.Width ~ Sepal.Length, data = iris)
predict(fit, iris[1, ])

foreach(i = 1:10) %dorng% predict(fit, iris[i, ])

# Error in { : 
# task 1 failed - "lm object has no valid 'qr' component.

# Works
foreach(i = 1:10, .packages = "mgcv") %dorng% predict(fit, iris[i, ])

# No mistake anymore...
foreach(i = 1:10) %dorng% predict(fit, iris[i, ])

Expected behavior

I would have hoped that using "doFuture" would avoid passing arguments like .packages to foreach().
