Faulty detection of "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah-nagl fhtagn"

I'm pretty sure this famous phrase from H. P. Lovecraft's The Call of Cthulhu is NOT Irish.
```
irb(main):006:0> DetectLanguage.detect("Ph'nglui mglw'nafh Cthulhu R'lyeh wgah-nagl fhtagn")
=> [{"language"=>"ga", "isReliable"=>true, "confidence"=>5.01}]
```
