Title: fixing splitting of filter args to preserve an empty string arg

Without this pull request, tempo fails to execute the replace filter in:
```{{value | replace 'pattern', ''}}```
...because the regular expression used to trim the leading and trailing filter argument quotes can remove multiple quote characters, entirely eliminating the second argument.
