Error on gem build type-on-strap.gemspec

When updating the files to build the gem for #9 I encountered some issue:

WARNING:  See http:https://guides.rubygems.org/specification-reference/ for help
ERROR:  While executing gem ... (Gem::InvalidSpecificationException)
    ["_sass/type-theme.scss"] are not files

However I had replaced type-theme.scss by type-on-strap.scss on all necessary files. In my gemspec, I put as the files specification:

  spec.files         = `git ls-files -z`.split("\x0").select { |f| 
f.match(%r{^(assets|_layouts|_includes|_sass|LICENSE|README)}i) }

I got this error because I hadn't committed my updates with git yet.
Since I had changed type-theme.scss into type-on-strap.scss it couldn't find the file.

Indeed, in spec.files, this git ls-files indicates that it will directly look for the files using git.
