Fix spec helper on MacOS

[odlp]

If the detected path to Chrome includes spaces (which it does by default on MacOS) then the version logging in spec/spec_helper.rb would fail, preventing the test suite from running.

Running the following command: bundle exec rspec --dry-run

Before

An error occurred while loading spec_helper.
Failure/Error: puts `#{command.to_a.first} --version`

Errno::ENOENT:
  No such file or directory - /Applications/Google
# ./spec/spec_helper.rb:18:in ``'
# ./spec/spec_helper.rb:18:in `<top (required)>'

Suggested fix

Shellwords.escape escapes the spaces:

Shellwords.escape("/Applications/Google Chrome.app/Contents/MacOS/Google Chrome") # => "/Applications/Google\\ Chrome.app/Contents/MacOS/Google\\ Chrome"
