Break when space in directory

[paparent]

When there's a space in the project directory or even directory ancestor, it makes the test fail with the following error:

Vim:E475: Invalid value for argument cmd: '/home/....../vue' is not executable

I created a new project with pnpm create vue, enabled vitest, and kept the project name vue-project but renamed the folder afterwards to vue project.

Looks like the bug in adapter.build_spec(), where vim.split(binary, "%s+").
