Export incorrectly squashes the env path

[sbienkow-ninja]

It appears as though some commands, like tk export, try to wrongly make the path absolute, by squashing ../<something>/ into ./, which is not correct. Most other commands, like show, do work.

Env info

Using tanka v0.20.0 (latest at the time of writing)

Reproduction description

To reproduce, simply create tanka environment, then create a new, empty folder and from within it try to export your environment.

Having following structure:

$ tree . -L 2
.
├── other
└── something
    ├── environments
    ├── jsonnetfile.json
    ├── jsonnetfile.lock.json
    ├── lib
    └── vendor

5 directories, 2 files

Running the tk export from something works as expected, but running tk export exportdir ../something/environments/default results in tanka trying to export $PWD/environments/default (as if ../ caused ../something/ to be deleted and appended to $PWD).:

Exporting from something:

$ tk export ../something_export environments/default
Loading environments/default from /tmp/tanka_export_path/something/environments/default/main.jsonnet
Loaded environments/default from /tmp/tanka_export_path/something/environments/default/main.jsonnet, time elapsed: 5.195276ms

Exporting from other:

$ tk export ../other_export ../something/environments/default
Error: finding root: stat /tmp/tanka_export_path/other/environments/default/main.jsonnet: no such file or directory
