Update jForm.java

For _directory bigger than 8 the result was always empty because there was no passing filePath to absPath

I'm afraid I'm not right with my small change. The non-working part was only about DIRECTORY_DOCUMENTS case (case 13). Cases (case 9 ...case 12) modify the abspath to be returned directly. So in order to do it right, it's necessary to change

                case 13:
                    if (Build.VERSION.SDK_INT < 19)
                        filePath = getMyEnvDir(Environment.DIRECTORY_DOWNLOADS, forcePubl);
                    else
                        filePath = getMyEnvDir(Environment.DIRECTORY_DOCUMENTS, forcePubl);
                    break;

into

                case 13:
                    if (Build.VERSION.SDK_INT < 19)
                        filePath = getMyEnvDir(Environment.DIRECTORY_DOWNLOADS, forcePubl);
                    else
                        filePath = getMyEnvDir(Environment.DIRECTORY_DOCUMENTS, forcePubl);
                    absPath = filePath;
                    break;

I'm not suggesting a new commit neither delete one in order to not produce a new bug or to confuse everybody. Apologies :)
