Fix metatags not showing autocomplete results until after the first letter was typed. For example, typing `filetype:` didn't show any completions until another letter was typed. Now typing `filetype:` shows all available file types. This was because `filetype:` by itself wasn't recognized as a valid search before, since metatags always required a value. Now it is a valid search, so it's technically possible to search for `filetype:` by itself. In this case the metatag value will be the empty string, which will return no results because there are no posts where the filetype is the empty string. This sounds nonsensical, but it's potentially useful for metatags like the `source:` metatag, where searching for posts with an empty source does make sense. It was also technically possible before by searching for `source:""`, so making the value optional doesn't change anything.
