c# patch_toText + patch_fromText doesn't work

```
What steps will reproduce the problem?
1. Run this code with C# version

string text1 = "I like football\nI like baseball";
string text2 = "I like football\nI love baseball";

diff_match_patch dmp = new diff_match_patch();
List diff = dmp.diff_main(text1, text2);

List patchList = dmp.patch_make(diff);

string patchText = dmp.patch_toText(patchList);
List patchList2 = dmp.patch_fromText(patchText);
object[] ob = dmp.patch_apply(patchList2, text1);
string patchedStr = ob[0].ToString();

if (patchedStr != text2)
{
// patch didn't work
}

Inizia eseguendo la riproduzione C# segnalata con diff_main, patch_make, patch_toText, patch_fromText e patch_apply. Confronta patchedStr con text2 e traccia il round trip della serializzazione delle patch; l'issue è completata quando patch_fromText produce patch che patch_apply applica correttamente, in modo che patchedStr sia uguale a text2.
