Fix crashes/busy looping happening via index
Right now, with the `StdinReader` plugin enabled - you can crash/cause
busy looping of xmobar if the following html file is opened:
```
<html>
<head>
<title>hello <fn=1>string</fn> </title>
</head>
</html>
```
More details about this bug is here:
https://github.com/jaor/xmobar/issues/442#issuecomment-625706001
This MR also fixes another bug which produces a crash in xmobar if you
pass non integer items between fn:
<fn=crash>
