Change error message matcher to work with all versions of ruby parser
Change error message matcher to work with all versions of ruby parser

Travis CI would run the spec suite with the newest version of Ruby parser 3.14.0 and we would see these errors:

       expect(file_traverser.parse_error_paths)
         .to match_array(['user.rb - RubyParser::SyntaxError - unterminated regex meets end of file. near line 1:'])

       expected collection contained:  ['user.rb - RubyParser::SyntaxError - unterminated regex meets end of file. near line 1:']
       actual collection contained:    ['user.rb - RubyParser::SyntaxError - unterminated regexp meets end of file. near line 1:']
