nix-build --store only finds NIX_PATH locations cached locally (2.1.1)

[LisannaAtHome]

Attempting to build a nix expression with nix-build --store will fail if the expression references a <path> that has not been cached on the local machine. For example:

NIX_PATH=foobar=https://example.com/nixexprs.tar.xz nix-build --store ssh-ng://root@example.com -E 'with import <foobar> {}; baz'

Will result in something like:

error: file 'foobar' was not found in the Nix search path (add it using $NIX_PATH or -I), at (string):1:13

Workaround: first run the nix-build command without the --store option, so that the <path> is downloaded and cached on the local machine. After this finishes and it starts building, interrupt the build and re-run the command with the --store option added.

This seems similar to #2053

Dup of #2085 (fixed for chroot stores and deemed "not easy to fix" for remote stores)?
