fix(feat): disable_automatic_asset_installation (#1226)

* fix(feat): `disable_automatic_asset_installation`

This fixes a regression in the feature system:
The asset installation didn't get turned off by the feature.

Add error logging to the install functions.

Properly show features in setup

disable `mkdir` in `wasm_vm` on `feature-disable-asset-installation`

Alternative:
    Is this even needed? We make sure the directory is there upon the
    normal asset installation.

fixes #1130
