fix: Fix function in resource fetcher that produced the same name for different requires in development mode (#396)

## Description

When loading two models using require the 2nd would overwrite the 1st
one, cause this function produced the same name for them. It worked for
remote URLs that were different in path part (the one divided by
slashes), but locally loaded files only differ by GET params, that were
cut off by split('?')[0]. This fixes it.

It might be considered breaking change in a sense it may change names of
models in the current app, so models will redownload
