Description

tika configuration when saving a fetcher with a list of strings will look like this:

      <httpHeaders>[]</httpHeaders>
      <httpRequestHeaders>[Authorization: xyz123]</httpRequestHeaders>

These are invalid format. It's expecting them to be:

      <httpHeaders></httpHeaders>
      <httpRequestHeaders>
          <httpRequestHeader>Autorization: xyz123</httpRequestHeader>
      </httpRequestHeaders>

So the effect of this is all List<String> configs in fetchers are completely ignored after being saved/re-read.
