Got errors when building a package with jsonpath lib: /github.com/oliveagle/jsonpath/jsonpath_test.go:1182: Fatal call has possible formatting directive %v /github.com/oliveagle/jsonpath/jsonpath_test.go:1185: Fatal call has possible formatting directive %v /github.com/oliveagle/jsonpath/jsonpath_test.go:1188: Fatal call has possible formatting directive %v /github.com/oliveagle/jsonpath/jsonpath_test.go:1235: Fatal call has possible formatting directive %v

t.Fatal should be t.Fatalf for above lines. My go version is 1.10.2 and it works fine with version 1.9.4.
