Bug: Windows doesn't know how to load files from within a tool without bundlepath

this works on Linux + macOS:

renoise.app():load_instrument("Presets/file.xrni")

Windows doesn’t. It demands

renoise.app():load_instrument(renoise.tool().bundle_path .. "/Presets/file.xrni")

is there any chance Windows could work too, @taktik

EDIT: i mean, either all of them should demand bundle_path inclusion
or then none of them should demand bundle_path inclusion.
