[Tests] install_nvm_from_git: fix malformed test command (missing space before ])

`[ "${head_ref}" != "${avoid_ref}"]` is missing the space before the closing bracket,
so the shell prints `[: missing ']'` and the avoid_ref assertion never actually runs
(it is inside an `if` condition, so the error was non-fatal and silently disabled the check)
