📚 Description

This change checks whether or not the driver was provided to the storage mount point, as opts.driver in the createStorage method is reading the driver. As a result, in previous versions, if no driver was provided, the build errors (which I have tested thoroughly) as it's trying to import a non-existing package with no proper error handling (non-existing due to the driver being "undefined"). This fixes that issue by not trying to import the driver if it wasn't specified, and in stead warning the user that the storage was not mounted, therefore allowing the build process to continue and succeed. In addition, this improves the DX as this error message provides more info than the previous default "Cannot find package 'undefined'", which may be confusing for new developers.
